ACPL-H312-500E

Overview

The ACPL-H312-500E is a logic output optocoupler designed for IGBT gate drive applications. It features a push-pull output stage capable of delivering a maximum continuous output current of 2.5 A. The device operates with a single channel and utilizes an SOIC-8 (SSO) surface-mount package. Key electrical parameters include an isolation voltage of 3750 Vrms, a typical rise time of 0.05 µs, and a typical fall time of 50 ns. The forward voltage is specified at 1.5 V with a maximum forward current of 16 mA.

Feature Summary

• Integrated push-pull output stage provides high peak current capability for rapid IGBT switching.
• High isolation voltage rating ensures robust protection between control and power circuits.
• Low internal current consumption reduces overall system power requirements.
• Includes under-voltage lockout (UVLO) to prevent improper operation during low supply conditions.

Applications

• IGBT gate driving in industrial motor drives
• Inverter circuits for renewable energy systems
• Switch-mode power supplies requiring isolated control

Procurement Notes

Verify the specific suffix '500E' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and RoHS compliance status. Ensure that the ordering part number matches the exact pinout and insulation characteristics required by the design. Cross-reference the component marking with the official Broadcom Limited documentation to authenticate the source and prevent counterfeit components from entering the supply chain.

Selection Notes

Select this component when a high-speed, high-current isolated driver is required for IGBTs. The push-pull architecture eliminates the need for external pull-up resistors, simplifying the circuit design. Consider the 3750 Vrms isolation barrier for safety-critical applications. Verify that the input current limits and propagation delays align with the microcontroller or DSP interface capabilities in the target system design.
