ACPL-W343-560E

Overview

The ACPL-W343-560E is a single-channel MOSFET output optocoupler from the Broadcom ACPL series, designed for IGBT gate drive applications. It features a stretched SO-6 package and provides 5000 Vrms isolation voltage. The device operates with a forward current of 25 mA and a forward voltage of 1.55 V. Key timing parameters include a rise time of 43 ns and a fall time of 40 ns. Power dissipation is rated at 700 mW, with an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrated high-current gate driver output capable of sourcing 4A
• High isolation voltage rating of 5000 Vrms for robust noise immunity
• Optimized switching speed with 43 ns rise and 40 ns fall times

Applications

• IGBT gate driving in industrial motor drives
• Inverter circuits for power conversion systems
• Solid-state relay control interfaces

Procurement Notes

Verify the specific suffix '560E' against the manufacturer's latest datasheet to confirm packaging type and lead time requirements. Ensure compatibility with system isolation standards such as UL 1577 or IEC 60747 before finalizing procurement specifications.

Selection Notes

Select this component when high peak output current is required for direct IGBT driving without external buffers. Compare rise/fall times against system switching frequency limits. Confirm that the 5000 Vrms isolation meets the circuit's safety clearance requirements.

Part Context

This part belongs to the Broadcom ACPL family of optocouplers, specifically targeting gate drive applications. It differs from standard logic output variants by integrating a higher current capability stage, distinguishing it from lower-power models like the ACPL-W343-000E which lacks the integrated driver strength.

Replacement Considerations

Check for ACPL-W343-000E if lower current is acceptable. Verify pinout compatibility with existing PCB layouts before substituting.
