Optoisolators are used to provide electrical isolation between two parts of a circuit, typically inputs and outputs, which need to be protected from one another for safety or performance reasons. The ACPL-5701L-100 is a type of Optoisolator specifically in the category of Transistor, Photovoltaic Output. It is available in through-hole and surface mount packages.

The ACPL-5071L-100 has an input LED light source and an output phototransistor collector. The input LED is driven by the input circuit, and its light is detected across an isolation gap by the phototransistor. The output phototransistor collector current is depended on the intensity of the light, which allows an input signal to be used as the control or activation source.

The ACPL-5701L-100 has two primary application fields: 1. Galvanic isolation of a low power signal circuit from a high power signal circuit and 2. Creation of an interlock for preventing erroneous activation of a higher power device. ACPL-5701L-100 can be used to safely switch typically up to 250V and 1.5A maximum.

The ACPL-5701L-100 has several key features, including very high isolation voltage between input and output of 4000Vrms for 1 minute, a low power input of 2mW for LED drive, and a minimum CTR (Current Transfer Ratio) of 40% at minimum IF (Forward Current) of 1mA. This allows the ACPL-5701L-100 to provide a secure interlock between two circuits, making it an ideal component for many different applications.

The working principles of the ACPL-5701L-100 are derived from a photoelectric effect – the phototransistor collector current is directly proportional to the strength of the absorbed photons from the input LED source. This means that the output current of the ACPL-5701L-100 is dependent on the input LED current, which can be controlled by the input circuit. The output current can be adjusted by varying the input current.

In the ACPL-5701L-100, the phototransistor output has a very high gain, allowing even very small amounts of input current to drive a large amount of output current safely and reliably. This allows the ACPL-5701L-100 to provide isolation with only a very small input signal, making it a versatile and reliable component in a wide range of applications.

The ACPL-5701L-100 is a versatile, reliable optoisolator for providing electrical isolation between circuits and creating interlocks with high power applications. It has a very high isolation voltage and a low current input, making it an ideal component for many different applications.
