TLP2745 Photocoupler Surface Mount 6 Pin

TLP2745 Photocoupler Surface Mount 6 Pin 

The TLP2745 is a high-speed, low-power digital output photocoupler designed for applications that require galvanic isolation, fast data transmission, and excellent noise immunity. It integrates a high-efficiency infrared LED on the input side and a high-speed photodetector IC on the output side, providing reliable digital signal transfer across an electrical isolation barrier.

The device supports high-speed data rates (typically up to 25 Mbps), making it suitable for advanced digital communication, industrial control, and motor drive applications. Its high common-mode transient immunity (CMTI) ensures stable operation even in electrically noisy environments such as inverters, power converters, and switching power supplies.

Housed in a compact 6-pin surface-mount (SMD) package, the TLP2745 offers a small footprint for modern high-density PCBs while maintaining a high isolation voltage for user and equipment protection.
