ACPL-W349-560E

Overview

The ACPL-W349-560E is a single-channel logic output optocoupler designed for gate drive applications. It features an integrated photo IC output capable of delivering a peak current of 2.5 A and continuous current of 2 A. The device provides 5000 Vrms isolation voltage with a common mode transient immunity of 100 kV/µs. Typical propagation delays are 110 ns, while rise and fall times are 8 ns. It operates within a temperature range of -40°C to +105°C and is housed in a 6-SOIC package.

Feature Summary

• High-speed switching capability optimized for wide-bandgap semiconductor devices
• Robust insulation barrier ensuring high safety and noise immunity
• Integrated output stage simplifies driver circuit design

Applications

• Gate driving for Silicon Carbide (SiC) MOSFETs
• Gate driving for Gallium Nitride (GaN) transistors
• Insulated gate driving for IGBT modules

Procurement Notes

Verify the specific suffix against official Broadcom documentation to confirm exact packaging and environmental compliance status. Ensure the component matches the required isolation voltage rating and package dimensions for the target PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when high dv/dt immunity and fast switching speeds are required for modern power electronics. The 2.5 A peak output current supports direct driving of medium-power switches without external buffer stages. Consider the 5000 Vrms isolation rating for systems requiring strict galvanic separation between control and power domains.

Part Context

This device belongs to the ACPL-W349 series of high-performance gate drive optocouplers. It is engineered specifically to address the challenges of driving wide-bandgap semiconductors like SiC and GaN, which demand faster switching and higher noise immunity compared to traditional silicon devices. The series offers a compact solution for isolated power conversion topologies.
