TRANSISTOR
2SD1843
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
ABSOLUTE MAXIMUM RATINGS (Ta = 25°C)
