A MOSFET works by either letting current flow across its terminals or not depending on the voltage applied. It operates on an electrical field effect produced by the voltage applied across the semiconductor surface adjacent to the metal oxide layer. As a result, this allows the MOSFET to work as either a p-type or n-type.

How does a MOSFET work?
How does it work in theory? 1 The infinite high input impedance makes MOSFETs useful for power amplifiers. The devices are also well suited to high-speed switching applications. Some integrated circuits contain tiny MOSFETs and are used in computers. 2 Because the oxide layer is so thin, the MOSFET can be damaged by built up electrostatic charges. In weak-signal radio-frequency work, MOSFET devices do not generally perform as well as other types of FET.
Why are MOSFETs useful?
The infinite high input impedance makes MOSFETs useful for power amplifiers. The devices are also well suited to high-speed switching applications. Some integrated circuits contain tiny MOSFETs and are used in computers.
What is MOSFET transistor?
MOSFET stands for metal-oxide semico nductor field-effect transistor. It is a special type of field-effect transistor (FET). Unlike BJT which is ‘current controlled’, the MOSFET is a voltage controlled device. The MOSFET has “ gate “, “ Drain ” and “ Source ” terminals instead of a “base”, “collector”, and “emitter” terminals in a bipolar transistor.
How to use a MOSFET as a switch?
How to use MOSFET as a switch? To use a MOSFET as a switch, you have to have its gate voltage (Vgs) higher than the source. If you connect the gate to the source (Vgs=0) it is turned off. For example we have a IRFZ44N which is a “standard” MOSFET and only turns on when Vgs=10V – 20V.
What is a MOSFET?
A MOSFET may be thought of as a variable resistor, where the Gate-Source voltage difference can control the Drain-Source Resistance. When there is no applying voltage between the Gate-Source , the Drain-Source resistance is very high, which is almost like a open circuit, so no current may flow through the Drain-Source.
Why do we put load on the drain side of a MOSFET?
For N-channel MOSFET t he reason we usually put the load at the Drain side is because of the Source is usually connected to GND.
Why is there no current flow into a MOSFET?
Because of the isolation of the Gate there is no current flow into the MOSFET from Gate. When voltage is applied at the gate, it changes the width of the Drain-Source channel along which charge carriers flow (electron or hole). The wider the channel, the better the device conducts.

How do vape pens work?
Many people enjoy vape pens because of how easy they are to use. The devices operate by simply pressing a button or inhaling from them. When you do this, the ingredients inside of the vape pen will heat up and produce vapors which can then be inhaled by the user.
What is the primary component of a vape pen?
The primary component of every vape pen is the heating chamber.
How much does a vape pen cost?
Vape pens can range anywhere from $15 to $200, but there are also some options that fall in between those two ranges. It is important to find a pen that you can afford and still meets all of your needs.
What is the vapor production area?
The vapor production area is another component of a vape pen – it's a space where vapor can be released.
How long does a vape last?
The effects can last anywhere from 30 minutes to two hours depending on the substance being used and your personal preferences.
Do people use vape pens?

Can you use a vape pen on the go?
If you've ever been to a bar or nightclub when someone was smoking a cigarette, you know how inconvenient it can be – especially if the smoke is in your vicinity. Vape pens can be used on-the-go without bothering other people around you.
Why use a MOSFET?
The idea behind using a MOSFET is that the the actual physical switch you press doesn't need to take the full current - so the switches themselves can be more delicately built (i.e. cheaper) and don't suffer from the arcing and crud buildup that require regular maintenance on full mechanical mods. The physical switch only has to pass sufficient current to trigger the transistor. This does not mean that MOFSET mods can handle a higher current than mechanicals, as frequently the reverse is true.
What is an Eleaf Istick 21700?
Single 21700 battery with no regulation (you get what the battery is putting out). It is electronically switched and has a few basic protections.
How does a vaporizer work?
Once the hot plate reaches the ideal temperature, your herb should begin to vaporize.
What happens when you vape weed?
Abrams of UCSF and published in the journal Neurology produced some interesting findings. Abrams found that vaporizing weed just below the combustion temperature caused very little exposure to the toxic chemicals created by combustion. Moreover, there was no reduction in the high experienced by the weed users in the study.
How hot does vaporize marijuana get?
You now know that vaporizing marijuana involves heating it without combustion. In contrast, when you light up a joint, it burns the weed. When combusted, the weed can burn at a maximum temperature of an astonishing 2,000 degrees Fahrenheit! Remember, cannabinoids begin to vaporize at just 220 degrees ( THCA ). On the other hand, CBC has one of the highest combustion temperatures at 451 degrees. However, that’s still far below the temperature reached when smoking weed.
What is a weed vaporizer?
A weed vaporizer is a device designed to heat herbs or concentrate. There are portable and desktop vaporizers available that use one of two types of heating mechanisms (conductive and convective heating). These vaporizers extract the cannabinoids from the plant and convert them into vapor.
Why is conduction not good for weed vaporizer?
Conduction is not the best choice for a weed vaporizer. This form of heating tends to burn the herb because of its inefficient distribution of heat.
What temperature does cannabis vaporize?
Most cannabinoids start to vaporize at 285 degrees. However, many vaporizers have the option to heat the herb to 400 degrees or more.
How does convection work?
Instead, convection involves the passing of heated air over the plant material. After the air has reached the correct temperature , it is moved via inhalation or a fan to the component holding the herb or concentrate. It heats the product and converts its cannabinoids and terpenes into vapor without charring it.

How to Use MOSFET as A Switch?
- To use a MOSFET as a switch, you have to have its gate voltage (Vgs) higher than the source. If you connect the gate to the source (Vgs=0) it is turned off. For example we have a IRFZ44N which is a “standard” MOSFET and only turns on when Vgs=10V – 20V. But usually we try not to push it too hard so 10V-15V is common for Vgs for this type of MOSFET....
Types of MOSFET
- MOSFETs come in four different types. There are three main categories we need to know. 1. N-Channel (NMOS) or P-Channel (PMOS) 2. Enhancement or Depletionmode 3. Logic-Level or NormalMOSFET N-Channel– For an N-Channel MOSFET, the source is connected to ground. To turn the MOSFET on, we need to raise the voltage on the gate. To turn it off we need to connect t…

The Gate electrode is electrically insulated from the main semiconductor by a thin layer of insulating material (glass, seriously!). This insulated meta…
FAQ
- Heat Sink connected to the Drain?
Typically the heat sink on the back of a MOSFET is connected to the Drain! If you mount multiple MOSFETs on a heat sink, they must be electrically isolated from the heat sink! It’s good practice to isolate regardless in case the heat sink is bolted to a grounding frame. - What is the Body Diode For?
MOSFETs also have an internal diode which may allow current to flow unintentionally. The body diode will also limit switching speed. You don’t have to worry about it if you are operating under 1Mhz.
