2N7002 Datasheet: An Overview of this MOSFET IC

Transistors are an essential part of electronic circuits. Because of their unique properties, they suit many different applications. However, our focus is on one of them – the 2N7002 MOSFET (Metal Oxide Semiconductor Field Effect Transistor). The 2N7002 is a logic level N-channel MOSFET. Typically, it has a low current, voltage, and input capacitance. For this reason, it is a crucial part of power management applications. Here, we highlight the description, features, and other basics of the 2N7002 Datasheet.

2N7002 BRIEF DESCRIPTION

In brief, the 2N7002 is a type of N-channel MOSFET. Also, it is a logic-level gate drive source useful in reducing on-state resistance. In addition, the MOSFET has a small gate-to-source threshold voltage rated 2.1V. Therefore, it is ideal for 3.3V application circuits. This feature also means a high-switching performance. So, it is a ubiquitous part of compact applications.
