IC-PC-400-SMD

The PC400 SMD IC is a high-reliability optocoupler (optical isolator) used to provide electrical isolation between low-voltage control circuits and high-voltage power circuits. Utilizing an internal infrared LED and phototransistor, it enables safe signal transfer without direct electrical connection.

The PC400 is widely used in switch-mode power supplies (SMPS), inverter circuits, industrial automation equipment, relay driver circuits, microcontroller interfaces, and communication systems. It helps protect sensitive electronic components from voltage surges, electrical noise, and ground loop interference.

This IC is commonly found in feedback control circuits, power management systems, motor control boards, and embedded electronics where reliable isolation and signal integrity are required. Its excellent noise immunity makes it suitable for demanding industrial environments.

The compact SMD package allows the PC400 to be used in modern high-density PCB layouts and automated manufacturing processes. Engineers and technicians prefer it for its stable operation, long service life, and easy integration into electronic designs.
