ACPL-M72U-500E

Overview

The ACPL-M72U-500E is a high-speed optocoupler from Broadcom Limited featuring a single channel in an SOIC-5 surface-mount package. It delivers a data rate of 10 Mb/s with a 3750 Vrms insulation voltage and 25 kV/µs common-mode transient immunity. The device utilizes a push-pull output configuration, ensuring fast switching with rise and fall times of 10 ns each. It operates within a temperature range of -40°C to +125°C, supporting a forward current of 10 mA and a reverse voltage of 5 V.

Feature Summary

• High-speed digital isolation with 10 Mb/s data transmission capability
• Robust noise immunity provided by 25 kV/µs common-mode transient rejection
• Push-pull output stage for precise signal integrity and fast switching

Applications

• Industrial automation control systems requiring galvanic isolation
• Power supply feedback loops for isolated voltage regulation
• Communication interfaces demanding high-speed signal transfer across isolation barriers

Procurement Notes

Verify the specific suffix '500E' to confirm RoHS compliance and tape-and-reel packaging format. Ensure the SOIC-5 footprint matches the target PCB design. Confirm that the 3750 Vrms isolation rating meets the safety requirements of the end application. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when both high data rates and strong noise immunity are critical. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to phototransistor alternatives. Consider the wide operating temperature range for harsh industrial environments. Verify that the 10 mA forward current requirement aligns with the driving source capabilities.

Part Context

This part belongs to the ACPL-M series of high-speed optocouplers designed for demanding digital isolation applications. The series emphasizes speed and reliability, utilizing advanced LED and detector technology. The ACPL-M72U variant specifically targets applications needing fast response times and high common-mode noise rejection in compact packages.

Replacement Considerations

Direct replacements must match the 10 Mb/s speed, push-pull output type, and SOIC-5 package. Verify equivalent CMTI ratings and isolation voltages. Cross-reference with other Broadcom M-series parts or competitors offering identical pinouts and electrical specifications to ensure functional compatibility.
