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

Broadcom ACPL-244-500E Quad Channel Optocoupler is a surface-mount, quad-channel phototransistor optocoupler with 3kV input-output isolation, housed in a compact SOIC-16 package.

Overview

The ACPL-244-500E integrates four separate phototransistors, optically coupled to two inversely parallel light-emitting diodes. This design supports reliable signal transmission between circuits operating at different potentials and impedances, providing galvanic isolation within signal transmission lines.

Key Specifications

• Input-output isolation voltage: 3000Vrms (3kV)
• Minimum current transfer ratio (CTR): 20%
• Forward current (If): up to 50mA
• Non-saturated response time: 2μs typical
• Common-mode rejection (CMR): 10kV/μs typical

Applications

This optocoupler is designed for industrial automation and digital interfacing. It serves as an I/O interface component in programmable logic controllers (PLCs), sequence controllers, computers, and various system appliances, helping to prevent ground loops and protect sensitive logic circuits from high-voltage transients.

Approvals and Construction

The device is certified to IEC/EN/DIN EN 60747-5-2 standards and is cUL approved. Its half-pitch, surface-mount design supports PCB assembly.

Choose the Broadcom ACPL-244-500E Quad Channel Optocoupler when you need four isolated channels in a single SOIC-16 package for high-speed signal isolation in control and industrial electronics.
