ACPL-M61T-000E

Overview

The Broadcom ACPL-M61T-000E is a high-speed, single-channel digital optocoupler designed for automotive applications. It features a Schottky-clamped open-collector logic output and supports data rates up to 10 MBd. The device provides robust isolation with a maximum rating of 4000 Vrms and a common-mode transient immunity (CMTI) of 15 kV/µs. It operates within an extended temperature range from -40°C to 125°C. Key electrical parameters include a typical propagation delay of 75 ns, a maximum forward voltage of 1.85 V, and a peak output current capability of 50 mA.

Feature Summary

• High common-mode transient immunity of 15 kV/µs for noise-resistant signal transmission
• Automotive-grade qualification compliant with AEC-Q100 standards
• Schottky-clamped open-collector output structure for reliable logic interfacing
• Wide operating temperature range suitable for harsh environmental conditions

Applications

• Automotive electronic control units (ECUs)
• Inverter gate drive circuits
• Industrial motor control systems
• Power supply feedback loops

Procurement Notes

Verify the specific suffix '000E' to ensure correct packaging and lead time specifications. Confirm that the 5-pin SO package aligns with your PCB footprint requirements. Check for RoHS compliance status and ensure the component meets the required automotive quality certifications for your specific application environment before finalizing procurement orders.

Selection Notes

Select this component when high-speed digital isolation is required in noisy environments. The 15 kV/µs CMTI rating makes it suitable for applications with rapid voltage changes, such as motor drives. Ensure the input current does not exceed the maximum rated value of 10 mA. Consider the open-collector output configuration for compatibility with pull-up resistor networks in your target circuit design.

Part Context

This part belongs to the ACPL-M61 series of high-speed optocouplers. It is distinct from variants like the ACPL-M61L or ACPL-M61M, which may differ in output type or insulation voltage ratings. The M61T variant is specifically optimized for automotive reliability and wide temperature operation, distinguishing it from standard industrial grade counterparts.

Replacement Considerations

Direct substitutes include other parts within the ACPL-M61 family, such as the ACPL-M61L-000E or ACPL-M61M-000E, provided their specific electrical characteristics match the system requirements. Verify pinout compatibility and insulation voltage ratings before substitution.
