ACNU-3410-500E

Overview

The ACNU-3410-500E is a single-channel gate drive optocoupler manufactured by Broadcom Limited. It features a peak output current of 3A and supports supply voltages from 15V to 30V. The device provides 5000Vrms isolation voltage with a typical propagation delay of 150ns. It utilizes an 8-SMD extended SOIC package, offering high common-mode transient immunity of 100kV/µs. Operating temperatures range from -40°C to 105°C, ensuring reliability in demanding industrial environments.

Feature Summary

• High peak output current capability of 3A for robust gate driving
• Rail-to-rail output voltage swing for precise signal transmission
• Integrated undervoltage lockout (UVLO) with negative supply reference
• Extended creepage and clearance distances for enhanced safety isolation

Applications

• Industrial motor control systems
• Inverter and converter gate drive circuits
• High-voltage power supply isolation interfaces
• Solid-state transformer driver applications

Procurement Notes

Verify the specific suffix 'E' indicates RoHS compliance and halogen-free status as per manufacturer standards. Confirm the package variant matches the required 8-SMD extended footprint dimensions. Ensure the ordering code aligns with the correct tape-and-reel quantity specifications for automated assembly processes.

Selection Notes

Select this component when high peak current drive is required alongside strict isolation requirements. The integrated UVLO feature simplifies design for negative supply rail configurations. Consider the 11mm creepage distance for applications requiring significant physical separation between high-voltage domains without additional barrier structures.

Part Context

This device belongs to the ACNU series of gate drive optocouplers designed for space-constrained, high-voltage industrial applications. It complements other Broadcom isolators by providing dedicated high-current output stages. The series focuses on reducing system complexity by integrating protection features directly into the optocoupler package.

Replacement Considerations

Direct substitutes include the ACNW3410-500E within the same product family. Verify pin compatibility and electrical parameter equivalence before substitution. Cross-reference datasheets to ensure identical isolation voltage ratings and package mechanical dimensions.
