IL5

Transistor, Photovoltaic Output Optoisolators Overview

The IL5 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a transistor output with base access. It provides an isolation voltage of 5300Vrms and operates within a temperature range of -55°C to 100°C. The device utilizes a 6-DIP package for through-hole mounting. Key electrical parameters include a maximum DC forward current (If) of 60 mA, a typical forward voltage (Vf) of 1.2 V, and a collector-emitter saturation voltage (Vce(sat)) of 400 mV maximum. The minimum current transfer ratio is 100% at 10 mA input.
