TLP781F(GR-TP7,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP781F(GR-TP7,F) 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 in a four-lead plastic DIP package featuring a 10.16mm lead pitch. The device provides high isolation voltage of 5000 Vrms minimum, ensuring reliable signal transmission between circuits operating at different voltage potentials. Key electrical characteristics include a collector-emitter breakdown voltage of 80V, a maximum forward current of 60mA, and a typical current transfer ratio ranging from 100% to 300% for the GR rank. Switching performance is defined by a typical rise time of 2µs and fall time of 3µs.
