ACPL-T350-500E

Overview

The ACPL-T350-500E is a single-channel logic output optocoupler from Broadcom Limited, designed for high-speed gate drive applications. It integrates a GaAsP LED with an internal IC featuring a power output stage capable of delivering up to 2.5A peak current. The device operates within a temperature range of -40°C to +100°C and provides 3750Vrms isolation voltage. Key electrical parameters include a forward voltage of 1.5V typical, reverse voltage of 5V, and power dissipation of 295mW. Propagation delay is specified at 500ns, supporting efficient switching in industrial and automotive environments.

Feature Summary

• Integrates a GaAsP infrared LED optically coupled to an integrated circuit with a dedicated power output stage for direct gate driving.
• Provides robust electrical isolation with a rated insulation voltage of 3750Vrms between input and output circuits.
• Delivers high peak output current capability of 2.5A to effectively drive IGBTs and MOSFETs in power conversion systems.

Applications

• IGBT gate drive circuits in motor control and inverters
• MOSFET gate drive applications in power supplies
• Industrial automation and control systems requiring isolated switching

Procurement Notes

Verify the specific suffix '500E' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with AEC-Q100 automotive qualification requirements if used in vehicle electronics. Cross-reference pinout configurations with the SOIC-8 or DIP-8 footprint depending on the exact variant ordered to prevent assembly errors.

Selection Notes

Select this component when high peak current drive (2.5A) is required for fast-switching power devices. Consider the 500ns propagation delay for timing-sensitive applications. Evaluate the 3750Vrms isolation rating against system safety standards. Compare power dissipation limits with thermal management capabilities in the final enclosure design.

Part Context

This part belongs to the ACPL-T350 series of high-speed optocouplers. It is manufactured by Broadcom Limited under the Avago brand lineage. The series is engineered for reliable performance in noisy electrical environments, offering enhanced common-mode transient immunity compared to standard logic output optocouplers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other 2.5A gate driver optocouplers only after confirming pinout, isolation voltage, and package dimensions match exactly.
