TLP624-4(LF1,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP624-4(LF1,F) is a four-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a gallium arsenide infrared emitting diode with a phototransistor to provide electrical isolation. The device features a minimum collector-emitter voltage of 55V and an isolation voltage of 5000Vrms. Key electrical parameters include a current transfer ratio ranging from 100% to 1200% at 1mA input, a maximum DC forward current of 50mA, and a typical switching time of 10µs on and 8µs off. It operates within a temperature range of -55°C to 100°C.
