ACPL-W347-500E

Overview

The ACPL-W347-500E is a single-channel logic output optocoupler from Broadcom's ACPL series, housed in a 6-pin SO stretched package. It features an integrated photo IC for rail-to-rail output capability and supports 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 typical rise time of 8 ns, a typical fall time of 8 ns, and a maximum propagation delay of 110 ns. The forward voltage is specified at 1.55 V with a maximum forward current of 25 mA.

Feature Summary

• Integrated photo IC output structure enabling rail-to-rail signal transmission
• High-speed performance with 8 ns typical rise and fall times
• Robust insulation rated at 5000 Vrms for safety isolation
• Compliance with UL 1577, CSA, and IEC/EN/DIN EN 60747-5-5 standards

Applications

• Gate drive circuits for power electronics
• Industrial motor control systems
• Power supply feedback loops

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration, as variations exist between bulk and reel formats. Confirm that the component meets RoHS directives if environmental compliance is mandatory for the assembly process. Ensure the supplier provides valid certification documents for the 5000 Vrms isolation rating to guarantee adherence to safety standards during integration.

Selection Notes

Select this component when high-speed switching and strong load driving capability are required. The 1 A output current capacity allows direct interfacing with certain gate drivers without additional buffering. Consider the 6-pin SO stretched package for surface-mount assembly constraints. Evaluate the 5000 Vrms isolation level against system safety requirements to ensure adequate protection between low-voltage control and high-voltage power stages.

Part Context

This device belongs to the ACPL series of optocouplers, designed for applications requiring reliable galvanic isolation. It utilizes GaAsP technology for the emitter and integrates a photo IC on the receiver side. The part is engineered to replace older discrete solutions by combining speed and drive strength in a compact form factor suitable for modern dense PCB layouts.

Replacement Considerations

Direct substitutes within the same family include the ACPL-W347-000E, which shares identical electrical characteristics but may differ in packaging quantity or tape-and-reel specifications. Verify pinout compatibility and thermal performance before swapping components in existing designs.
