SFH6186-4T Description

Short technical summary and product information.

The Vishay Dale SFH6186-4T 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 applications in telecom, industrial controls, battery-powered equipment, and office machines.

 

Key electrical specifications include a high isolation test voltage of 5300 VRMS and a maximum collector emitter voltage (VCEO) of 55V. The current transfer ratio (CTR) typically ranges from 160% to 320% at a forward current of 1mA, with a minimum CTR of 63% at the same condition. The typical forward voltage is 1.5V, and the maximum collector current is 100mA.

 

This optocoupler operates within a temperature range of -55C to +100C. It is housed in an SMD-4 package with dimensions of 4.83mm in length, 6.81mm in width, and 3.81mm in height. The mounting type is SMD/SMT, and it comes in a cut tape packaging format. The lead spacing is 2.54mm, allowing for end-stackable configurations.

 

The SFH6186-4T is RoHS3 compliant, has an MSL of 1, and is REACH unaffected, though these compliance statuses are based on low-confidence sources and should be verified.
