TLP383(BL-TPL,E

Transistor, Photovoltaic Output Optoisolators Overview

The TLP383(BL-TPL,E is a single-channel phototransistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED and a phototransistor in an LSOP4 package to provide electrical isolation between input and output circuits. The device features a maximum collector-emitter voltage of 80 V and a continuous collector current rating of 50 mA. Key electrical parameters include a forward current of 50 mA, a typical forward voltage of 1.25 V, and a saturation voltage of 300 mV. The current transfer ratio ranges from 200% to 600% at a forward current of 5 mA. Switching characteristics are defined by a turn-on time of 3 µs and a turn-off time of 3 µs. The unit supports an insulation voltage of 5000 Vrms and operates within a temperature range of -55°C to +125°C.
