SFH617A-3 Description

Short technical summary and product information.

The Vishay SFH617A-3 is a high-reliability optocoupler designed for signal transmission between electrically separated circuits. It features a GaAs infrared diode emitter optically coupled to a silicon planar phototransistor detector, housed in a 4-DIP package.

 

Key electrical specifications include an isolation test voltage of 5300 Vrms, a maximum collector emitter voltage of 70 V, and a forward current of up to 60 mA. The current transfer ratio ranges from a minimum of 100% to a maximum of 200% at 10mA. It offers fast switching times with typical turn-on and turn-off times of 3µs and 2.3µs respectively, and typical rise and fall times of 2µs.

 

This optocoupler is rated for an operating temperature range of -55°C to +110°C, making it suitable for demanding environments. The 4-DIP package is through-hole mountable, with a standard lead spacing of 0.300 inches (7.62mm).

 

Applications for the SFH617A-3 include AC adapters, SMPS, PLCs, factory automation, and game consoles, where high isolation and reliable signal transfer are critical.
