ACPL-W349-000E

Overview

The Broadcom ACPL-W349-000E is a high-speed gate drive optocoupler designed for driving SiC and GaN devices. It features a single channel with an integrated photo IC output. Key electrical parameters include a maximum continuous output current of 2.5 A, an isolation voltage of 5000 Vrms, and a forward voltage of 1.55 V. The device supports a maximum input current of 25 mA and operates within a temperature range of -40°C to +105°C.

Feature Summary

• High-speed gate drive capability optimized for wide-bandgap semiconductors
• Integrated photo IC output structure for direct driver interfacing
• High common-mode transient immunity for noise-resistant operation

Applications

• Driving Silicon Carbide (SiC) power switches
• Driving Gallium Nitride (GaN) power switches
• Industrial networking systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix '000E' against the official datasheet to confirm package type and lead-free status. Ensure the application circuit matches the 2.5A output current rating and 5000Vrms isolation requirements. Cross-reference the operating temperature range of -40°C to +105°C with system thermal constraints before finalizing procurement.

Selection Notes

Select this component when driving SiC or GaN devices requiring high-speed isolation. The 2.5A peak output current suits medium-power gate drive applications. Consider the 6-SO package for surface-mount assembly. Verify that the required isolation voltage meets or exceeds the system's 5000Vrms specification.
