ACPL-W347-000E

Overview

The ACPL-W347-000E is a high-speed gate drive optocoupler from the Broadcom ACPL series, designed for driving Silicon Carbide (SiC) and Gallium Nitride (GaN) power devices. It features an AlGaAs LED optically coupled to an integrated circuit with a power output stage capable of delivering a maximum continuous output current of 1 A. The device provides 5000 Vrms isolation voltage and operates within a temperature range of -40°C to +105°C. Key electrical parameters include a rise time of 8 ns, a fall time of 8 ns, and a maximum propagation delay of 110 ns. It utilizes a SO-6 Stretched package with a power dissipation rating of 550 mW.

Feature Summary

• Integrated power output stage optimized for high-speed switching applications
• High common-mode transient immunity suitable for noisy environments
• Wide operating temperature range supporting industrial and automotive conditions

Applications

• Gate driving for Silicon Carbide (SiC) MOSFETs
• Gate driving for Gallium Nitride (GaN) HEMTs
• Industrial motor control systems
• High-frequency DC-DC converters

Procurement Notes

Verify the specific suffix code to ensure compatibility with required isolation standards and packaging options. Confirm that the SO-6 Stretched footprint matches the target PCB design constraints. Check for RoHS compliance documentation if environmental regulations apply to the end product. Ensure input current limits are respected during system design to maintain device longevity.

Selection Notes

Select this component when high-speed isolation is required for wide-bandgap semiconductors. The 1 A output current capability supports direct gate driving without additional buffer stages in many configurations. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the thermal performance given the 550 mW power dissipation limit under worst-case operating conditions.

Part Context

This part belongs to the ACPL-W347 series, which is part of Broadcom's broader portfolio of logic output optocouplers. The series is specifically engineered to address the demands of modern power electronics using SiC and GaN technologies. It shares architectural similarities with other high-speed gate drive optocouplers but offers distinct timing characteristics tailored for efficient switching control.

Replacement Considerations

Direct substitutes may include other Broadcom ACPL-W34x variants or comparable high-speed gate drive optocouplers from other manufacturers offering similar 1 A output current and 5000 Vrms isolation. Verify pinout compatibility and electrical parameter equivalence before substitution.
