Optoisolators are electrical devices used to isolate an input signal\'s electrical energy from the output of output signals and from any other external influences. They provide a complete physical insulation between the two sections. In terms of their application field and working principle, PS8802-2-A optoisolators belong to the category of optoisolators featuring transistor and photovoltaic output.

The PS8802-2-A optoisolator consists mainly of a light-emitting diode (LED) paired with a phototransistor. When a signal is applied to LED, the photon energy it emits is focused by its glass lens and it triggers the photodiode of the phototransistor. When the phototransistor is activated, current is applied to the output terminal, thereby producing the required effect.

In general, the PS8802-2-A type optoisolators are designed to achieve a current-to-voltage conversion ratio of up to 100A/V. This makes them suitable for applications such as industrial relay and HVAC systems. Moreover, they are designed to operate over a wide range of temperatures, ranging from -55°C to +125°C, making them suitable for use in extreme temperature environments.

The PS8802-2-A optical isolators have an excellent isolation performance, with isolation voltage ratings up to 3000 Vrms. These optoisolators provide excellent level of protection against electrical noise, EMI, ESD, and surge disturbances, enabling the devices to operate without problems even in the most demanding industrial applications. They have a very fast response time in the order of few microseconds, which makes them ideal for use in time-critical applications.

The PS8802-2-A optoisolators have a typical electrical life of up to 100,000 cycles and a typical optical life of up to 500,000 cycles. They also offer high temperature stability, with a 0.1%/°C maximum variation in performance. Additionally, these optoisolators feature ultra-low power consumption and are UL listed.

In conclusion, the PS8802-2-A optoisolators belong to the family of optoisolators featuring transistor and photovoltaic output. Their main components are an LED and a phototransistor, and they offer a current-to-voltage conversion ratio of up to 100A/V. They can operate in extreme conditions such as very low and high temperatures and they provide an excellent isolation performance rated at up to 3000 Vrms. They also offer excellent electrical and optical life, and feature ultra-low power consumption.
