ACPL-P343-000E

Overview

The ACPL-P343-000E is a single-channel MOSFET output optocoupler featuring a push-pull output stage designed for gate drive applications. It provides an isolation voltage of 3750 Vrms and operates within a temperature range of -40°C to +105°C. The device supports a maximum forward current of 16 mA with a typical forward voltage of 1.55 V. Electrical performance includes a typical rise time of 43 ns and a fall time of 40 ns. It is housed in a 6-pin SO-6 Stretched surface-mount package.

Feature Summary

• Integrated push-pull output stage providing rail-to-rail output voltage swing for efficient IGBT and MOSFET gate driving.
• High isolation capability rated at 3750 Vrms, ensuring robust signal transmission between isolated circuits.
• Fast switching characteristics with typical propagation delays suitable for high-frequency power conversion systems.

Applications

• Variable-speed drives
• Electric vehicles
• Induction cookers
• Solar inverters

Procurement Notes

Verify the specific suffix '000E' to confirm RoHS compliance and lead-free status as per Broadcom specifications. Ensure the SO-6 Stretched package footprint matches the target PCB design. Confirm that the 3750 Vrms isolation rating meets the safety requirements of the end application. Cross-reference the datasheet revision date to ensure all electrical parameters are current before finalizing component selection.

Selection Notes

Select this component when a push-pull output topology is required for driving IGBTs or MOSFETs directly. The 16 mA input current limit defines the driver circuit requirements. The 3750 Vrms isolation level determines the creepage and clearance constraints on the PCB layout. Consider the 4A output current capability against the total gate charge of the target power switch to ensure adequate drive strength during switching transitions.

Part Context

This part belongs to the Broadcom ACPL series of gate drive optocouplers. It is distinct from the ACPL-W343 variant, which features an IGBT collector output rather than a push-pull configuration. The ACPL-P343 is specifically engineered for applications requiring symmetric drive signals and high-speed switching performance in isolated power electronics environments.

Replacement Considerations

The ACPL-W343-000E is a related device but utilizes an IGBT collector output instead of a push-pull output. Substitution requires verifying if the load circuit can accommodate the different output topology. No other direct pin-compatible substitutes are confirmed in the provided documentation.
