ACPL-W314-500E

Overview

The ACPL-W314-500E is a single-channel high-speed optocoupler featuring an integrated IGBT gate driver output stage. It provides electrical isolation between control logic and power devices, supporting supply voltages from 10V to 30V. The device delivers a minimum peak output current of 0.4A and a maximum of 0.6A, suitable for directly driving small to medium power IGBTs and MOSFETs. Key electrical parameters include a typical forward voltage of 1.5V at a maximum input current of 25mA, with a maximum propagation delay of 0.7μs across the temperature range. It offers a minimum common mode rejection of 25kV/μs and operates within a temperature range of -40°C to +100°C.

Feature Summary

• Integrated push-pull output stage capable of sourcing and sinking up to 0.6A peak current for direct gate drive
• Ultra-high common mode rejection ratio (CMR) of 25kV/μs ensures reliable operation in high-noise environments
• High-speed response with low propagation delay suitable for PWM applications up to 10MHz
• Bootstrappable supply current design simplifies circuit topology for half-bridge configurations

Applications

• Isolated gate drive for IGBTs and Power MOSFETs in motor control inverters
• AC and brushless DC motor drives
• Industrial inverters and variable frequency drives
• Switching power supplies (SPSs)
• Inverter systems for home appliances and induction cookers

Procurement Notes

Verify the specific suffix '500E' corresponds to the required insulation rating and safety approvals. Confirm that the SO-6 stretched package dimensions match the PCB footprint requirements. Ensure the operating environment temperature range aligns with the specified -40°C to +100°C limits. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when direct drive capability for IGBTs or MOSFETs is required without external discrete transistors. The 25kV/μs CMR makes it suitable for noisy industrial inverter environments. Consider the 10V-30V supply range compatibility with available bootstrap circuits. The single-channel configuration is ideal for half-bridge legs where space efficiency is prioritized over multi-channel integration.

Part Context

This part belongs to the Broadcom ACPL series of optocouplers, specifically designed for power electronics applications. It integrates a GaAsP LED with a specialized output IC to provide robust signal isolation and power delivery. The W-series designation typically indicates enhanced insulation ratings compared to other variants in the family, meeting stringent safety standards like UL1577 and IEC/EN/DIN EN 60747-5-5.

Replacement Considerations

Public confirmed substitutes include the ACPL-P314-500E, which shares similar functionality but may differ in specific insulation voltage ratings (3750 Vrms vs 5000 Vrms). Verify pinout compatibility and thermal characteristics before substitution. Other members of the ACPL-W314 family may offer different packaging options or slight parameter variations.
