ACPL-M61T-500

Overview

The ACPL-M61T-500E is a single-channel high-speed optocoupler from Broadcom's ACPL series, housed in a 5-pin SO package. It features a DC input and an open collector logic output with Schottky clamping. Key electrical parameters include a typical rise time of 24ns, a typical fall time of 10ns, and a maximum forward voltage of 1.85V. The device supports a data rate of 10MBd and offers an isolation voltage of 4000Vrms. It operates within a temperature range of -40°C to 125°C and complies with AEC-Q100 automotive standards.

Feature Summary

• High-speed signal transmission capability supporting 10MBd data rates for efficient digital communication.
• Robust insulation performance with 4000Vrms isolation voltage ensuring safe separation between circuits.
• Integrated Schottky clamping on the open collector output to prevent saturation and enhance switching speed.
• Automotive-grade reliability certified under AEC-Q100 standards for use in demanding environments.

Applications

• Industrial automation control systems requiring fast response times
• Automotive electronics meeting AEC-Q100 qualification requirements
• Power supply feedback loops for isolated voltage regulation

Procurement Notes

Verify the complete part number suffix, such as '500E', to ensure correct packaging and compliance status. Confirm that the specific variant matches the required isolation voltage and output configuration. Check for RoHS3 compliance and AEC-Q100 certification if automotive applications are intended. Ensure the supplier provides official datasheets matching the exact component designation to avoid functional mismatches.

Selection Notes

Select this component when high-speed isolation is critical for system performance. The open collector output requires external pull-up resistors, which must be accounted for in the circuit design. Consider the 1.85V maximum forward voltage drop for drive current calculations. The 5-pin SO package limits pin count, so verify footprint compatibility during PCB layout. Evaluate the 15kV/µs CMTI rating against noise levels in the application environment.

Part Context

This device belongs to the Broadcom ACPL series of optocouplers, designed for high-performance isolation applications. The ACPL-M61T variant specifically targets markets needing rapid signal transfer with reliable galvanic isolation. It complements other members of the family by offering a balance of speed and robustness in a compact surface-mount form factor suitable for dense electronic assemblies.

Replacement Considerations

The ACPL-M61M-500E is a documented alternative within the same product line, featuring push-pull output instead of open collector. Verify that the change in output topology does not impact existing circuit designs requiring pull-up components. Both parts share similar isolation ratings and package types, facilitating potential cross-referencing if supply constraints arise.
