BROADCOM ACPL-244-500E Quad Channel Optocoupler, SOIC-16, 3kV

The BROADCOM ACPL-244-500E is a surface-mount, quad-channel phototransistor optocoupler designed for high-performance signal isolation. Featuring a compact SOIC-16 package, it integrates four separate phototransistors optically coupled to two inversely parallel light-emitting diodes. This design ensures reliable signal transmission between circuits with different potentials and impedances, making it a cornerstone component for robust industrial electronics.

A key specification is its high input-output isolation voltage of 3000Vrms (3kV), providing critical protection against voltage surges and ensuring safe operation in demanding environments. The device offers a minimum current transfer ratio (CTR) of 20% and supports a forward current (If) of up to 50mA. Its non-saturated response time is a rapid 2μs typical, facilitating high-speed data transmission in control systems.

Core Applications

This optocoupler is widely deployed in industrial automation and digital interfacing. It serves as an essential I/O interface component in programmable logic controllers (PLCs), sequence controllers, computers, and various system appliances. Its primary function is to provide galvanic isolation in signal transmission lines, preventing ground loops and protecting sensitive logic circuits from high-voltage transients.
