TLP385(BL,E

Transistor, Photovoltaic Output Optoisolators Overview

The TLP385(BL,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a gallium arsenide infrared emitting diode with a silicon phototransistor within a compact 6-SO (4-lead) surface-mount package. The device provides high isolation capability rated at 5000Vrms between input and output circuits. Key electrical specifications include a maximum collector-emitter voltage of 80V, a continuous forward current of 50mA, and an output channel current capacity of 50mA. Typical switching performance features turn-on and turn-off times of 3µs, with rise and fall times of 2µs and 3µs respectively. The unit operates across a wide temperature range from -55°C to 110°C.
