PS9634 POWER TRANSISTOR DRIVING BASE AMPLIFIER BUILT-IN TYPE PHOTOCOUPLER

DESCRIPTION
The PS9634 and PS9634L are optical linkage devices mounting a GaAs infrared ray LED on the light emitting side
(input side) and a photo diode and a signal processing circuit on the light receiving side (output side) on one chip.
They can directly drive a power transistor of 15 to 20 A class used for such as an inverter control air conditioner or
general purpose inverter.
The PS9634L has a surface mount type lead.
