2N4401 Description

The 2n4401 is a bipolar junction transistor with an NPN junction that is used for general purpose amplification and switching. Conduction is carried out by both charge carriers, i.e. electrons and holes, in a bipolar junction transistor. However, electrons will be the majority charge carriers.

2N4401 Features

The collector current (IC) is 500mA on a continuous basis.

The voltage between the collector and the emitter (VCE) is 40 volts.

The collector-base voltage (VCB) is set to 60 volts.

6V is the Emitter Base Breakdown Voltage (VBE).

100MHz is the transition frequency.

To-92 package is available.

General-purpose NPN Transistor

High DC Current Gain (hFE), typically 80 when IC=10mA
