C3987 datasheet



The C3987 is 50V, 3A, NPN Planar Silicon Darlington Transistor.


1. High DC current gain.

2. Large current capacity and wide ASO.

3. On-chip Zener diode of 60±10V between collector and base.

4. Uniformity in collector-to-base breakdown voltage due to the adoption of an accurate impurity diffusion process.

5. High inductive load handling capability.

6. Micaless package facilitating mounting.

Absolute Maximum Ratings at Ta = 25°C

1. Collector-to-Base Voltage : VCBO = 50 V

2. Collector-to-Emitter Voltage : VCEO = 50 V

3. Emitter-to-Base Voltage : VEBO = 6 V

4. Collector Current : IC = 3 A

5. Collector Current (Pulse) : ICP = 6 A

6. Base Current : IB = 0.6 A


C3987 Pinout



1. Suitable for use in switching of L load (motor drivers, printer hammer drivers, relay drivers).
