NPN SILICON EPITAXIAL TRANSISTOR (DARLINGTON CONNECTION)

FOR LOW-FREQUENCY POWER AMPLIFIERS AND LOW-SPEED SWITCHING

The 2SD1843 is a Darlington connection transistor with on-chip

dumper diode in collector to emitter and zener diode in collector to

base. This transistor is ideal for use in acuator drives such as

motors, relays, and solenoids.

FEATURES

• High DC current gain due to Darlington connection

• High surge resistance due to on-chip protection elements:

C to E: Dumper diode

C to B: Zener diode

• Low collector saturation voltage
