Working Principle

The SFH6156-3T Transistor, Photovoltaic Output optoisolator is able to electrically isolate two circuits by using a photovoltaic cell and a transistor output stage. This type of optoisolator is composed of two separate parts: an infrared LED and transistor output stage. The infrared LED emits light when connected to an input power source, and the transistor output stage converts the emitted light into a current signal. This current signal can then be used to control and power loads in the secondary circuit.

The SFH6156-3T optoisolator is also designed with a special feature that allows it to maintain its isolation properties even when the input signal becomes large. This special feature helps to protect the circuit from overvoltaged input signals that could potentially harm other components in the circuit. Additionally, this optoisolator is also designed with built-in over temperature and overcurrent protection, ensuring that the device does not become damaged due to excessive current or heat.

The SFH6156-3T Transistor, Photovoltaic Output optoisolator is a versatile, cost-effective way to electrically isolate circuits from one another. It is able to provide high levels of isolation protection while also reducing noise, controlling sensitive circuits, and providing stable performance over time. Thanks to its wide range of features, the SFH6156-3Toptoisolator is an ideal choice for a variety of opto-isolating applications.
