2N7002 MOSFET Datasheet – Specifications, Features & Applications

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.
