ACPL-355JC-500E

Overview

The ACPL-355JC-500E is a high-performance gate driver optocoupler designed for driving IGBTs and SiC MOSFETs in power conversion applications. It features integrated fault protection, feedback, and diagnostics within a 16-pin SOIC package. The device provides non-inverting high-side and low-side drive signals with a peak output current of 10A. It offers 5 kVrms isolation voltage and operates over an extended temperature range from -40°C to 105°C.

Feature Summary

• Integrated fail-safe diagnostics and fault reporting for IGBT and SiC MOSFETs
• High-speed signal transmission with dedicated high-side and low-side outputs
• Robust insulation performance suitable for demanding industrial environments

Applications

• Industrial motor drives and inverters
• Switched-mode power supplies (SMPS)
• Solar inverter systems
• Uninterruptible power supply (UPS) units

Procurement Notes

Verify the specific suffix 'JC' against official Broadcom documentation to confirm pinout compatibility and functional specifications. Ensure that the required isolation voltage ratings align with the target application's safety standards. Confirm availability status as components may be subject to supply constraints or lifecycle changes.

Selection Notes

Select this component when integrated fault detection and high-current gate driving capabilities are required in a single isolated package. Consider the 16-pin SOIC form factor for PCB layout constraints. Evaluate the need for active Miller clamp functionality if present in the datasheet to prevent false triggering during high dv/dt events.

Part Context

This part belongs to the ACPL-355 series of gate driver optocouplers from Broadcom Limited. It is engineered specifically for high-power switching applications requiring reliable isolation between control logic and power stages. The series emphasizes diagnostic features to enhance system reliability and simplify design implementation.

Replacement Considerations

Consult official Broadcom substitution guides for direct replacements. Verify that any alternative part number matches the 16-pin SOIC footprint, 5 kVrms isolation rating, and 10A peak drive current requirements.
