ACPL-M72U-000E

Overview

The ACPL-M72U-000E is a high-speed logic output optocoupler from Broadcom's R²Coupler series, designed for robust digital isolation. It features a single channel with a Photo IC output type housed in an SOIC-5 package. The device supports data rates up to 10 Mb/s and provides an insulation voltage of 3750 Vrms. Key electrical parameters include a forward current of 10 mA, forward voltage of 1.5 V, and reverse voltage of 5 V. Output characteristics specify a maximum output current of 4 mA and power dissipation of 40 mW. Transition times are rated at 10 ns for both rise and fall. Operating temperatures range from -40°C to +125°C.

Feature Summary

• High-speed digital isolation capability with 10 Mb/s data rate
• Robust common-mode transient immunity of 25 kV/µs
• Logic output configuration using Photo IC technology
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial automation control systems
• Power supply feedback loops
• Communication interface isolation
• Motor drive gate driver circuits

Procurement Notes

Verify the specific suffix '000E' to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm that the SOIC-5 through-hole or surface-mount variant matches the intended PCB layout, as package handling differs. Cross-reference the datasheet revision date to ensure compatibility with current design specifications and regulatory updates. Ensure sourcing channels provide authentic components to avoid counterfeit risks associated with high-demand isolation devices.

Selection Notes

Select this component when high-speed signal transmission is required alongside strong noise immunity in electrically noisy environments. The 25 kV/µs CMTI rating makes it suitable for applications with rapid voltage changes, such as inverters or motor drives. Consider the 10 Mb/s speed limit against system timing requirements. The single-channel architecture is ideal for simple isolation tasks where multiple channels are unnecessary. Evaluate thermal management needs based on the 40 mW power dissipation rating under maximum load conditions.

Part Context

This part belongs to the ACPL-M72 series, which focuses on high-performance optocouplers for demanding industrial applications.
