Broadcom AC Input 2-Channel Surface Mount Photodarlington Optocoupler 8-Pin SO HCPL-0731-500E

Broadcom HCPL-0731-500E is a dual channel AC input optocoupler designed with surface mount technology in an 8-pin SO package. It features a separated pair of GaAsP light-emitting diodes optically coupled to integrated high gain photo detectors, delivering exceptional signal isolation and transmission performance.

This optocoupler offers a typical high current transfer ratio of 1800% with a maximum rating of 2600%, enabling efficient and reliable signal processing in demanding industrial and electronic component applications. The device supports input currents up to 40 mA and operates effectively over a wide temperature range from -40°C to 85°C.

The low input current of 0.5 mA and output saturation voltage of just 0.1 V makes the HCPL-0731-500E energy efficient while maintaining strong performance. It is designed to provide excellent input-output common mode transient immunity and low output saturation voltage thanks to a dedicated pin for the photodiodes and first gain stages (VCC).

This optocoupler is compatible with LSTTL logic outputs and is packaged in reels that are perfect for surface mount automated assembly processes. Its robust isolation voltage rating of 3750 Vrms makes it suitable for applications requiring electrical isolation such as power supplies, communications, instrumentation, and industrial controls.

Common uses include electronic isolation in circuits for industrial automation, communication systems, and power management equipment. The device is UL, CSA, and VDE approved, assuring compliance with key industry standards. Manufactured in the Philippines, it reflects high manufacturing and quality standards.
