TLP731(GB-LF2,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP731(GB-LF2,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared LED input coupled to a phototransistor output within a DIP-6 package. Key electrical parameters include a collector-emitter breakdown voltage (VCEO) of 55V minimum, a maximum forward current (IF) of 60mA, and a collector current (IC) of 50mA. The device offers a high current transfer ratio (CTR) ranging from 50% to 600% at IF=5mA and VCE=5V. It supports an isolation voltage (BVS) of 4000Vrms for one minute and operates within a temperature range of -55°C to 100°C.
