Optoisolators are solid-state devices that use a light emitting diode (LED) and a light detector to provide electrical isolation between two circuits. The MOC208R2VM is an optoisolator in the Transistor, Photovoltaic Output family of devices. It is designed for superior optical performance with an extremely low leakage current, and low power dissipation, and is suitable for a variety of applications.

MOC208R2VM has two pins: one emitter pin and one photovoltaic output pin. The emitter pin provides a current controlled optical output. The photovoltaic output pin provides a voltage output proportional to the current in the emitter pin, and this output is separated from the emitter input. The MOC208R2VM isolator has an emission strength (intrinsic diode) of 25 A. The insulation barrier between the emitter and photovoltaic output pins is 56 Vrms. Additionally, the device has internal ESD protection, faster response time, and strong optical crosstalk immunity.

The MOC208R2VM is ideal for analog signal transmission, industrial loads control, operational amplifier (op-amp) feedback loop feedback, and other applications where reliable isolation, high accuracy, and low-current consumption are necessary. Furthermore, it offers very fast response time, low power dissipation, and superior optical performance.

The working principle of the MOC208R2VM optoisolator relies on the current-controlled light output of the emitter pin and its corresponding photovoltaic output when its light is incident upon the output device. The emitter pin provides a current-controlled optical output of 25 A. When the optical output of the emitter pin incident upon the photovoltaic output pin, a voltage-proportional to the incident light intensity is generated. This voltage is used to control the output device, such as a transistor, thereby providing galvanic isolation between the two pins.

The photovoltaic output pin of the MOC208R2VM optoisolator can be used to drive a variety of loads. The device can be used to drive transistors, FETs, thyristors, and other high-current loads. Additionally, it can be used in analog signal transmission, such as converting audio signals into voltage signals, and can be used in industrial loads control, such as controlling motors, heating elements, and other devices. Moreover, it can be used in operational amplifier (op-amp) feedback loops for stable loop response.

The MOC208R2VM is a versatile device with superior optical performance, high current output capacity, low leakage current,fast response time, and strong crosstalk immunity. It is an ideal choice for applications where reliable electrical isolation and circuit protection is needed, such as analog signal transmission, industrial loads control, and operational amplifier (op-amp) feedback loop feedback.
