BC140 datasheet



This is 1A, 40V, NPN Medium Power Transistor.

The BC140 and BC141 are silicon planar epitaxial NPN transistors in TO-39 metal case. They are particularly designed for audio amplifiers and switching applications up to 1A. The complementary PNP types are the BC160 and BC161.

Absolute maximum ratings :

1. Collector-base Voltage: Vcbo = 80 V

2. Collector-emitter Voltage: Vceo = 40 V

3. Emitter-base Voltage: Vebo = 7 V

4. Collector Current: Ic = 1 A

5. Base Current : Ib = 0.1 A

6. Channel temperature: Tch = 175 °C

7. Storage temperature: Tstg = -55 to +175 °C
