Optoisolators are electronic devices used to isolate electrical circuits from one another. They electrically isolate two circuits while allowing them to communicate with each other using light. Optoisolators help maintaining signal integrity in a circuit and reduce electrical noise, which could cause a device to malfunction. The PC852XNNSZ0F optoisolator is a 4-channel optoisolator of the Transistor, Photovoltaic Output type.

Application Field

The PC852XNNSZ0F optoisolator is designed for use in a wide range of application fields, from medical devices, telecommunications equipment, industrial equipment and automation, aerospace and military equipment, to consumer electronics and automotive control systems. Its small SO-8 package size allows it to be used in constrained spaces, providing an optimal signal integrity solution. It also meets UL insusceptibility requirements ensuring safety. Its exceptional thermal stability and high level of reliability also make it ideal for applications that operate in extreme conditions.

Working Principle

The PC852XNNSZ0F optoisolator has four channels that are designed to detect signals from the input side and provide high current outputs on the output side. Each channel consists of a PIN photodiode, a phototransistor, and a filter resistor. The PIN photodiode detects an external signal and converts it into an electrical signal, which is then amplified and filtered by the phototransistor. The filter resistor limits the transients and noise at the output. The phototransistor provides a high current output that is equal to the signal input. The output can then be used to interface with external devices such as motors, relays, LEDs, etc.

The PC852XNNSZ0F is designed to be electrically isolated from the input and output sides. This ensures that any noise generated on the output side is not propagated back to the input side. The optoisolator also has an LESD (Light Emitting Silicon Diode) protection circuit that can protect against high voltages and surges. This helps to protect both the optoisolator and the circuit in which it is used.

The PC852XNNSZ0F optoisolator is a reliable and efficient solution for isolating circuitry in a wide range of applications. Its small size and high reliability make it ideal for use in limited spaces, and its electrical isolation ensures signal integrity. It is also designed with protection mechanisms to ensure the safety of the circuitry it is used in.
