SFH620A-3 Description

Short technical summary and product information.

The Vishay Dale SFH620A-3 is an optocoupler featuring a GaAs infrared diode emitter optically coupled to a silicon planar phototransistor detector. It is designed for signal transmission between two electrically separated circuits and is suitable for AC input applications.

 

Key electrical specifications include an isolation test voltage of 5300 VRMS and a high collector-emitter voltage (VCEO) of 70 V. The current transfer ratio (CTR) for the SFH620A-3 ranges from 40% to 125% at a forward current of 10 mA, with typical values reaching 100%.

 

This optocoupler is housed in a DIP-4 package with 400 mil spacing and option 6, offering creepage and clearance distances greater than 8 mm. It complies with IEC 60950 for reinforced insulation up to an operating voltage of 400 V RMS or DC. The device is end-stackable with 2.54 mm lead spacing and offers high common-mode interference immunity.
