PS2801A-1-M-A

Overview

The PS2801A-1-M-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a compact SSOP-4 surface-mount package. The device provides electrical isolation with a rated insulation voltage of 2500 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80V, a maximum forward current of 30mA, and a collector current capacity of 50mA. The unit operates across a temperature range of -55°C to +100°C.
