ACPL-M61U-500E

Overview

The ACPL-M61U-500E is a high-speed logic output optoisolator manufactured by Broadcom Limited. It features a single channel with a data rate of 10 MBd and an isolation voltage of 3750 Vrms. The device utilizes an open collector, Schottky-clamped phototransistor output. Key electrical parameters include a propagation delay of 75 ns, a maximum forward current of 8 mA, and a typical forward voltage of 1.33 V. It operates within a temperature range of -40°C to 125°C and is housed in a 5-SOIC package.

Feature Summary

• High-speed data transmission capability at 10 MBd for efficient signal isolation.
• Robust insulation performance rated at 3750 Vrms for safety-critical applications.
• Schottky-clamped open collector output design ensures fast switching and noise immunity.

Applications

• Industrial automation control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Communication interfaces needing high common-mode transient immunity

Procurement Notes

Verify the specific suffix 'U' corresponds to the open collector configuration and 5-SOIC package when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors or Broadcom. Ensure the procurement documentation matches the exact part number to avoid confusion with similar ACPL-M61 variants that may have different output types or packaging options.

Selection Notes

Select this component when a push-pull output is not required and an open collector interface is preferred for wired-OR configurations or level shifting. The 10 MBd speed suits moderate-to-high frequency digital isolation needs. Consider the 3750 Vrms isolation rating against system voltage requirements. Verify that the 8 mA forward current limit aligns with the driving circuit capabilities.

Part Context

This part belongs to the Broadcom ACPL-M61 series of high-speed optocouplers. The series offers various output configurations including push-pull and open collector options. The ACPL-M61U variant specifically provides the open collector output type, distinguishing it from other members like the ACPL-M61M which features a push-pull output. All variants share similar isolation and speed characteristics.

Replacement Considerations

Direct substitutes include other ACPL-M61 series parts with identical open collector outputs and 5-SOIC packaging, such as the ACPL-M61U-000E if available. Cross-reference pinouts and electrical specifications carefully before substitution to ensure compatibility with existing circuit designs.
