IL766B-1

Transistor, Photovoltaic Output Optoisolators Overview

The IL766B-1 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a photodarlington transistor output. It provides an isolation voltage of 5300Vrms and operates within a temperature range of -55°C to 100°C. The device accepts both AC and DC input signals. Key electrical parameters include a typical forward voltage (Vf) of 1.25V, a maximum DC forward current (If) of 60 mA, and a maximum output voltage of 60V. The saturation voltage drop (Vce) is limited to 1V maximum. It exhibits a minimum current transfer ratio of 900% at 500µA input current. Typical switching characteristics include an on/off time of 200µs. The component is housed in a 6-DIP package with a width of 0.300 inches (7.62mm).
