ACFL-3161T-000E

Overview

The Broadcom ACFL-3161T-000E is an automotive-grade gate drive optocoupler designed for high-performance power switching applications. It features a single channel with rail-to-rail output capability and delivers a peak output current of 10 A. The device provides 5 kV RMS isolation voltage and supports a wide operating supply voltage range from 15 V to 30 V. Key electrical parameters include a maximum propagation delay of 95 ns, a maximum dead-time distortion of 35 ns, and a minimum common-mode transient immunity (CMTI) of 100 kV/μs at V_CM = 1000 V. It operates within an industrial temperature range of -40 °C to +125 °C and consumes a maximum supply current of 4 mA.

Feature Summary

• AEC-Q100 Grade 1 qualified for automotive reliability standards
• High peak output drive current of 10 A for direct SiC MOSFET or IGBT driving
• Robust noise immunity with 100 kV/μs CMTI and low input impedance LED
• Integrated hysteresis-based undervoltage lockout (UVLO) protection

Applications

• Powertrain DC-DC converters in electric vehicles
• On-board chargers for EVs and PHEVs
• Automotive isolated gate drivers for inverters and HVAC systems
• Industrial motor drives and renewable energy inverters

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration as per official documentation. Confirm that the component meets AEC-Q100 Grade 1 requirements for the intended automotive application environment. Ensure compatibility with the required 15 V to 30 V supply voltage range and check for valid safety certifications such as UL 1577 and IEC 60747-5-5 before final integration.

Selection Notes

Select this component when high-speed switching with minimal distortion is critical for efficiency in SiC or IGBT applications. The SO-12 package offers a compact footprint suitable for space-constrained designs while maintaining high creepage and clearance distances. Consider the 10 A peak current capability for driving larger power devices directly without additional buffer stages.
