ACPL-W343-500E

Overview

The ACPL-W343-500E is a single-channel MOSFET output optocoupler from the Broadcom ACPL series, designed for gate drive applications. It features an IGBT collector output type and operates within a temperature range of -40°C to +105°C. Key electrical parameters include a maximum continuous output current of 4A, an isolation voltage of 5000 Vrms, and a forward voltage of 1.55V at a forward current of 25mA. The device exhibits a typical rise time of 43ns and a fall time of 40ns, with a power dissipation rating of 700mW. It is housed in a 6-pin SO-6 Stretched surface-mount package.

Feature Summary

• Provides optical isolation for gate drive signals in switching applications
• Features high isolation voltage capability for reliable signal transmission
• Designed for driving IGBT collectors and power components

Applications

• Industrial automation systems
• Control of power components in industrial settings
• Gate drive circuits requiring optical isolation

Procurement Notes

Verify the specific suffix '500E' against official Broadcom documentation to confirm exact pinout and packaging variations. Ensure compatibility with existing PCB footprints for the SO-6 Stretched package. Confirm that the 5000 Vrms isolation rating meets the safety requirements of the target application environment. Cross-reference thermal management needs given the 700mW power dissipation limit.

Selection Notes

Select this component when high-speed gate drive isolation is required for IGBTs or MOSFETs. The 4A output current capability supports direct driving of many power devices. Consider the 43ns/40ns transition times for switching frequency requirements. The wide operating temperature range suits harsh industrial environments. Verify input current limits do not exceed 25mA in the design phase.

Part Context

This part belongs to the Broadcom ACPL series of optocouplers, which are widely used for providing electrical isolation between control circuits and power stages. The W343 variant specifically targets gate driver applications, offering a balance of speed and current drive capability. It complements other logic and transistor output optocouplers in the portfolio by addressing high-power switching needs.
