FAQs

What is 2N3738?

The 2N3738 is a high-voltage, high-speed NPN bipolar junction transistor (BJT) designed for general-purpose switching and amplification applications. It is commonly used in power supply circuits, motor drivers, and switching circuits.

How Does 2N3738 Work?

The 2N3738 operates as a voltage-controlled switch or amplifier, where a small input voltage or current at the base terminal controls a larger current flow between the collector and emitter. This enables the transistor to switch high voltages and currents or amplify weak signals with high voltage gain.

How Many Pins does 2N3738 have and What are the Functions of the Pinout Configuration?

The 2N3738 is housed in a TO-126 package, which typically includes three pins: the collector, base, and emitter. The pinout configuration is as follows:

Collector (C): This pin connects to the positive supply voltage in typical operating configurations.
Base (B): The control input pin where the smaller input signal is applied to control the transistor's operation.
Emitter (E): This pin is the ground reference for the transistor and the output terminal for the controlled current flow.
