ACPL-W346-060E

Overview

The ACPL-W346-060E is a single-channel logic output optocoupler designed for gate drive applications. It features a rail-to-rail output capable of delivering up to 2.5A peak current, suitable for driving Power, GaN, and SiC MOSFETs. The device provides 5000Vrms isolation voltage with VDE and LF certifications. Key electrical parameters include a maximum propagation delay of 120ns, typical rise and fall times of 8ns, and a continuous output current rating of 1A. It operates within a temperature range of -40°C to +105°C and is housed in a 6-pin SO-6 Stretched package.

Feature Summary

• High-speed rail-to-rail output stage optimized for direct gate driving of wide-bandgap semiconductors
• Enhanced safety isolation with VDE and LF certifications supporting high-voltage switching environments
• Integrated design combining fast signal transmission with robust power delivery capabilities

Applications

• Gate driving for Silicon Carbide (SiC) MOSFETs
• Gate driving for Gallium Nitride (GaN) transistors
• Isolated control interfaces for high-power silicon MOSFETs

Procurement Notes

Verify the specific suffix code to ensure correct isolation certification levels, as variants exist with different voltage ratings such as 3750Vrms or 5000Vrms. Confirm that the 6-SO stretched package footprint matches the target PCB layout requirements. Ensure supply chain sources provide original manufacturer documentation to validate component authenticity and traceability for industrial applications.

Selection Notes

Select this component when high peak current capability is required for rapid switching of wide-bandgap devices. Compare against lower-current variants if only standard silicon MOSFETs are used. Consider thermal management requirements due to power dissipation characteristics. Verify that the input forward voltage and current limits align with the available drive circuitry specifications before integration.

Part Context

This part belongs to Broadcom's ACPL-W346 series, which focuses on isolated gate drivers. The series distinguishes itself by offering higher output currents compared to standard logic optocouplers. It serves as a bridge between low-power control logic and high-power switching stages, ensuring electrical safety while maintaining signal integrity in demanding power electronics systems.

Replacement Considerations

ACPL-P346-060E offers similar functionality but with lower peak output current (1A vs 2.5A) and different isolation ratings. ACPL-W346-500E provides alternative isolation voltage options. Verify pin compatibility and thermal performance when substituting, as output drive strength differences may impact switching speeds in sensitive circuits.
