Do not forget N-channel Logic Level MOSFET-2N7002

Published time: 2019-01-08

Guide:Hello, friends, last time, jotrin electronics engineer explained to us the N-channel hexfet power mosfet-IRF3205, about the related details,features and so on.

This time we will continue to introduce new electronic components for you. It is an N-channel Logic Level MOSFET called 2N7002. The 2N7002 has always played an important role in the electronics industry. I hope this brief introduction will help you better understand it. 

In this post,you will know that what is the 2N7002,about its features,applications and other related benefits.

The 2N7002 is a low voltage, low current Logic Level N-channel MOSFET. Because of its low on-state resistance and low input capacitance,we can use in power management applications. The MOSFET can be controlled by 3.3V or 5V system voltage,due to his low threshold voltage.

If you have any question,you can consult with our engineers.Let's have a look! Hope you can get information that is valuable to you.

The simple description of 2N7002

2N7002 is a N-channel Logic Level MOSFET,which belong to Discrete Semiconductor Products,

I prefer to classify it as transistors.A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.

The 2N7002 is a logic level MOSFET with a low on-state resistance. The mosfet has a low gate to source threshold voltage of 2.1V. This makes the mosfet suitable even for 3.3V application circuits. Since the mosfet has low on state resistance,it has high efficiency during when the mosfet in on. Due to this property it can maintain high switching performance and hence used widely in power management applications.

The mosfet also comes in a SMD package hence can be used for compact applications. One considerable disadvantage of the mosfet is its low drain current; it can provide a continuous current of 200mA and peaks currents upto 1A at maximum threshold voltage. Anything more than that will damage the mosfet.

The 2N7002 we bought on the market, mostly produced by famous semiconductor manufacturers-on Semiconductor, using SOT-23 (TO-236AB) package,Operating Temperature range is between -55°C ~ 150°C,the Power Dissipation (Max) is 200mW.

The description of Pin Configuration 

2N7002 has three pins, which are Source, Gate, and Drain. They correspond to different functions. For specific description about 2N7002 pin, please refer to 2N7002 datasheet. You can free download 2N7002 Pdf at the end of the article.

Pin Configuration about 2n7002

When we need 2N7002, we found that there is no such component, how to deal with it?

Once this happens, we need to understand the relevant properties of the 2N7002 and then find the replacement electronic components, which means that this replacement component has the same functionality and properties as the 2N7002.
