ACPL-P346-500E

Overview

The Broadcom ACPL-P346-500E is a single-channel logic output optocoupler designed for high-performance gate driving applications. It integrates an AlGaAs LED with an IC featuring a power output stage capable of delivering up to 2.5 A peak current. The device operates within a temperature range of -40°C to +105°C and utilizes a 6-pin SO stretched package. Key electrical parameters include a maximum forward voltage of 1.95 V, typical rise and fall times of 8 ns and 30 ns respectively, and an isolation voltage of 3750 Vrms.

Feature Summary

• Integrates a high-speed AlGaAs LED with a dedicated power output stage for efficient signal transmission.
• Provides robust galvanic isolation between input control circuits and high-voltage power stages.
• Features rail-to-rail logic outputs suitable for direct interfacing with various driver topologies.

Applications

• Gate drive circuits for Power MOSFETs
• Gate drive circuits for Silicon Carbide (SiC) MOSFETs
• Gate drive circuits for Gallium Nitride (GaN) transistors

Procurement Notes

Verify the specific suffix '500E' against official Broadcom documentation to confirm packaging configuration and material compliance status. Ensure that the procurement channel provides valid traceability records. Cross-reference the component marking with the datasheet to prevent counterfeit substitution. Confirm that the delivered units match the specified 6-SO stretched package dimensions and pinout arrangement.

Selection Notes

Select this component when high peak output current capability is required for driving fast-switching wide-bandgap semiconductors. The choice depends on the need for rapid propagation characteristics and high isolation voltage ratings. Evaluate thermal management requirements based on the specified operating temperature range. Consider the package footprint constraints during PCB layout design to ensure adequate clearance for the isolation barrier.
