VISHAY SFH690ABT Optocoupler, Transistor Output, SOP-4, 50mA, 3.75kV

The VISHAY SFH690ABT is a 1-channel, 4-pin phototransistor output optocoupler designed for reliable signal transmission between two electrically separated circuits. It combines a GaAs infrared emitting diode with a silicon planar phototransistor detector, offering a high current transfer ratio, low coupling capacitance, and high isolation voltage.

This optocoupler is engineered for high-density mounting and space-sensitive PCBs and PLCs, making it ideal for communications and networking applications. Key features include low saturation voltage, fast switching time, temperature stability, and an end-stackable 0.100” (2.54mm) spacing for compact designs.

With a high collector-emitter breakdown voltage of 70V and a reverse voltage of 6V, this component ensures robust performance in demanding environments. It is suitable for isolating and transferring signals in industrial control systems, communication interfaces, and networking equipment.
