Description

The C945, 2SC945 is an audio frequency amplifier high frequency OSC NPN transistor. This Transistor is a type of bipolar junction transistor (BJT) made from silicon, a semiconductor material. This transistor is designed for amplifying or switching electronic signals in various electronic circuits.

NPN Configuration

1. Emitter (N): The heavily doped N-type layer, which is the source of charge carriers (electrons) in the transistor.

2. Base (P): The thin P-type layer, which controls the flow of charge carriers between the emitter and collector.

3. Collector (N): The N-type layer, which collects the charge carriers that pass through the base-emitter junction.

Features

1. Collector-Emitter voltage :  V(br)CBO = 50V

2. Collector current up to 150mA

3. High hFE linearity

4. Complimentary to UTC 2SA733
