ACPL-331J-500E

Overview

The ACPL-331J-500E is a logic output optocoupler manufactured by Broadcom Limited, designed for high-speed signal transmission with integrated gate drive capabilities. It features a single channel housed in an SOIC-16 surface-mount package. The device provides an insulation voltage of 3750 Vrms and supports a maximum continuous output current of 1.5 A. Key electrical parameters include a rise time of 50 ns and a fall time of 50 ns. The forward current is specified at 12 mA, with a forward voltage of 1.95 V and a reverse voltage rating of 5 V. Power dissipation is rated at 600 mW, and the unit operates within a temperature range of -40°C to +105°C.

Feature Summary

• Integrated IGBT gate drive functionality supporting up to 1.5 A output current
• High-speed signal transmission with 50 ns rise and fall times
• Robust electrical isolation rated at 3750 Vrms
• Logic output configuration for direct interface with control circuitry

Applications

• IGBT gate driving in motor control inverters
• Power supply isolation interfaces
• Industrial automation control systems
• High-voltage switching applications

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes match project requirements. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet. Validate that the SOIC-16 footprint matches PCB design specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed isolation combined with direct gate drive capability is required. The 1.5 A output current suits medium-power IGBTs directly. Consider the 3750 Vrms isolation barrier for safety-critical designs. Evaluate thermal management needs given the 600 mW power dissipation rating in enclosed environments.

Part Context
