2N3904 NPN Transistor BJT

A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier

Features

• Bi-Polar NPN Transistor
• DC Current Gain (hFE) is 300 maximum
• Continuous Collector current (IC) is 200mA
• Base- Emitter Voltage (VBE) is 6V
• Collector-Emitter Voltage (VCE) is 40V
• Collector-Base Voltage (VCB) is 60V
• Available in To-92 Package

2N3904 Pin Configuration

Pin Number Pin Name Description

•  Emitter Current Drains out through emitter
•  Base Controls the biasing of transistor
•  Collector Current flows in through collector

Applications

• Driver Modules like Relay Driver, LED driver etc…
• Amplifier modules like Audio amplifiers, signal Amplifier etc…
• VCB and VBE is high hence can be used to control voltage loads up to 40V
• Commonly used in TV and other home appliances

Package Include

• 1x 2N3904 NPN Transistor BJT
