TLP385(E

Transistor, Photovoltaic Output Optoisolators Overview

The TLP385(E) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a gallium arsenide infrared emitting diode with a phototransistor within a compact 4-pin SO6L surface-mount package. The device provides high isolation voltage of 5000 Vrms, ensuring robust signal transmission across isolated circuits. Key electrical parameters include a collector-emitter voltage of 80V minimum, a DC forward current maximum of 50mA, and an output current capability of 50mA per channel. Typical switching characteristics feature turn-on and turn-off times of 3µs, with rise and fall times of 2µs and 3µs respectively. The unit operates reliably within a temperature range of -55°C to 110°C.
