VISHAY SFH6156-3T Transistor Output Optocoupler, 60mA, 5.3kV, SMD DIP

The VISHAY SFH6156-3T is a high-performance phototransistor output optocoupler, engineered for precise signal transmission between electrically isolated circuits. This device is built with a GaAs infrared diode emitter that is optically coupled to a silicon planar phototransistor detector, offering superior electrical isolation and data integrity. It boasts excellent current transfer ratio (CTR) linearity, which varies consistently with the forward current, ensuring reliable and predictable performance in a wide range of operating conditions.

A key benefit of this coupler is its fast switching times, making it suitable for high-speed digital signal applications. It is also designed for long-term stability with low CTR degradation over time and low coupling capacitance, which helps minimise interference and crosstalk in sensitive circuits. With an exceptionally high isolation voltage of 5.3kV, it provides robust protection and safety in systems where high voltage separation is critical.
