ACPL-M71T-500E

Overview

The ACPL-M71T-500E is a high-speed digital optocoupler manufactured by Broadcom Limited, designed for robust signal isolation in demanding environments. It features a single channel with a data rate of 10 Mb/s and a common-mode transient immunity of 15 kV/µs. The device operates within an extended temperature range from -40°C to +125°C and holds AEC-Q100 qualification for automotive applications. Key electrical parameters include a forward current of 10 mA, forward voltage of 1.5 V, and reverse voltage of 5 V. Output specifications support a maximum output current of 10 mA with rise and fall times of 10 ns each. The unit provides an insulation voltage of 4000 Vrms and consumes 40 mW of power dissipation. It is housed in a through-hole SOIC-5 package.

Feature Summary

• High common-mode transient immunity of 15 kV/µs ensures reliable operation in noisy environments.
• AEC-Q100 qualified for suitability in automotive electronic systems.
• Extended operating temperature range supports harsh thermal conditions.

Applications

• Hybrid and electric vehicle powertrain control
• Automotive battery management systems
• Industrial motor drive isolation

Procurement Notes

Verify the specific suffix '500E' against official Broadcom documentation to confirm exact packaging and tape-and-reel specifications. Ensure the procurement order matches the required automotive grade and AEC-Q100 certification status. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Confirm that the SOIC-5 package type aligns with the target PCB footprint requirements before finalizing the purchase order.

Selection Notes

Select this component when high-speed digital isolation is required alongside strict automotive reliability standards. The 10 Mb/s data rate suits applications needing rapid signal transmission across isolation barriers. Consider the 15 kV/µs CMTI rating for environments with significant voltage spikes. The wide temperature range makes it appropriate for under-hood or industrial settings where standard commercial parts may fail.

Part Context

This device belongs to the ACPL-M71T series of high-temperature digital CMOS optocouplers. The series is engineered for hybrid and electric vehicle applications requiring durable signal isolation. The ACPL-M71T-500E variant specifically addresses automotive-grade needs while maintaining high-speed performance characteristics typical of the broader family.

Replacement Considerations

The ACPL-M71T-000E is a documented substitute within the same product family. Verify pinout compatibility and parameter equivalence before substitution.
