Broadcom DC Input Optocoupler Surface Mount, 6-Pin SO, 1.95V Max Forward Voltage, 5000Vrms Isolation, ACPL-W50L-560E

The Broadcom ACPL-W50L-560E is a high-performance DC input optocoupler that ensures effective electrical isolation between low-voltage digital input signals and corresponding output systems. Housed in a compact stretched SO-6 surface-mount package, this device incorporates a light-emitting diode and a fast-response integrated photon detector, separated by a robust insulating layer for excellent galvanic isolation.

Engineered to withstand isolation voltages up to 5000Vrms, the ACPL-W50L-560E offers a maximum forward voltage of 1.95V, making it ideal for low power designs where efficiency and safety are crucial. The optocoupler supports a low input drive current starting at just 3mA, which, combined with a low propagation delay of 1μs at 5V, makes it suitable for high-speed digital signal transmission in dense electronic systems. Its open-collector output structure is TTL compatible, ensuring seamless interfacing with a wide array of digital circuits.

This component supports a flexible operating supply voltage range from 2.7V to 24V, enhancing compatibility across both logic-level and industrial system voltages. The ACPL-W50L-560E is rated for reliable operation across an extended ambient temperature range from -40°C to +105°C, delivering stable switching and insulation characteristics in demanding industrial, automation, and process control environments.

The optocoupler accommodates a single input channel and provides strong common-mode transient immunity (15kV/μs at VCM=1500V), protecting connected equipment from electrical transients and noise. Its SO-6 packaging is optimized for space-saving PCB layouts where surface mounting is required. The device's maximum input current specification is 40mA, with a current transfer ratio range of 93% to 200%, supporting efficient signal conversion and output response.

Key applications include PLC input and output modules, digital signal isolation for microcontrollers or FPGAs, automotive systems (without automotive standard marking), electronic instrumentation, and other areas where protection from electrical interference and safe isolation is required. The tape and reel packaging make this optocoupler suitable for automated assembly in high-volume manufacturing.

With internationally recognized approvals (CSA, UL, IEC/EN/DIN EN 60747-5-5, RoHS compliance), the ACPL-W50L-560E aligns with stringent quality requirements. The combination of low power operation, robust isolation, and fast switching makes it an industry-standard solution for safety and signal integrity in modern electronics.
