ACPL-312T-500E

Overview

The ACPL-312T-500E is a single-channel logic output optocoupler designed for gate drive applications. It features an 8-pin surface mount DIP package with gull-wing leads. The device provides electrical isolation between input and output circuits, supporting DC signal transmission. Key electrical parameters include a typical rise time of 500 ns and a fall time of 100 ns. It offers a high isolation voltage rating of 3750 Vrms. The component operates within a temperature range of -40°C to 125°C and complies with AEC-Q100 automotive standards.

Feature Summary

• Provides galvanic isolation for gate drive signals in power electronics
• Features fast switching characteristics suitable for high-frequency applications
• Complies with AEC-Q100 automotive qualification standards

Applications

• Industrial motor control systems
• Power supply gate driving
• Automotive electronic control units

Procurement Notes

Verify the specific suffix '500E' against official Broadcom documentation to confirm the exact timing specifications and packaging details. Ensure that the procurement source provides valid RoHS compliance certificates and traceability records consistent with automotive-grade requirements. Cross-reference the part number with the manufacturer's current product status to avoid obsolete inventory risks.

Selection Notes

Select this component when high-speed isolation is required for driving MOSFETs or IGBTs. The 500 ns rise time distinguishes it from faster variants like the ACPL-312J series. Consider the 8-pin SOIC package for PCB space constraints. Verify that the 3750 Vrms isolation level meets the system's safety insulation requirements.

Part Context

This part belongs to the Broadcom ACPL-312 family of gate driver optocouplers. It is distinct from the ACPL-M61T series, which utilizes a different 5-pin SO package and exhibits significantly faster switching speeds (24 ns rise time). The ACPL-312 series is specifically engineered for robust gate drive isolation rather than general-purpose logic signaling.

Replacement Considerations

The ACPL-312T-300E is a documented variant within the same family, offering similar functionality but potentially differing in packaging or specific timing parameters. Direct substitution requires verification of pinout compatibility and electrical parameter alignment with the original design specifications.
