IL250

Transistor, Photovoltaic Output Optoisolators Overview

The IL250 is a single-channel optoisolator manufactured by Vishay Semiconductor Opto Division, featuring a phototransistor output with an accessible base terminal. It provides a high isolation voltage of 5300Vrms and supports both AC and DC input signals. The device is housed in a 6-DIP package (0.300 inch / 7.62 mm width) designed for through-hole mounting. Key electrical specifications include a maximum forward current of 60 mA, a typical forward voltage of 1.2 V, and a maximum collector-emitter saturation voltage of 400 mV. It offers a minimum current transfer ratio of 100% at 10 mA input and operates within a temperature range of -55°C to 100°C.
