2N7000 N-Channel MOSFET, Features & Applications

The 2N7000 N-channel MOSFET is a small signal. These MOSFET’s are power electronic switches such as transistors, However, with a higher current and voltage grading. The 2N7000 MOSFET can be used to switch loads which works on less than 60V (VDS) and 200mA (ID). The Pin Configuration of 2N7000 N-Channel MosFET.

How we can use 2N7000:

A Mosfet has 3 terminals source, gate and Drain. Current always flows in through the Drain and Source. The Gate pin work as a switch for remain ON or OFF the mosfet. If the gate will be connected to ground then the mosfet will be off that there will be no connection among Drain and source. If the Gate is connected with positive point of battery than the MOSFET will be ON. Thus, by controlling the Voltage (VGS) we can change the Mosfet hence the MOSFET is a voltage controlled device. The Gate Source Voltage (VGS) is an important parameter while using the transistor. For 2N7000 transistor the VGS is 20V, so when we give this voltage the MOSFET will be fully off. Any values in among 20V is make the MOSFET to close partially thus creating a partial relation. The load which is being switched by the MOSFET can be upto 60volt and can used upto 200mA (ID)

Applications of 2N7000:

  • LED dimmers or flashers
  • Switching High voltage loads
  • Low power Analog converters or inverters
  • Commonly used for small signal switching
