SFH620A-2XG

Overview

The SFH620A-2XG is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features an AC input configuration utilizing inverse parallel infrared LEDs and an NPN silicon phototransistor output. The device provides high isolation with a rated voltage of 5300Vrms and a peak withstand voltage of 7500VPK. Electrical characteristics include a maximum collector-emitter saturation voltage of 0.4V at specified currents, typical rise and fall times of 4µs and 3µs respectively, and a current transfer ratio ranging from 100% to 320%. It is housed in a standard 4-pin DIP package.

Feature Summary
