Overview
The ACPL-K33T-500E is a single-channel automotive-grade logic output optocoupler from the Broadcom ACPL series. It features an R²Coupler architecture with SOIC-8 (6.8mm) surface-mount packaging. Key electrical parameters include a 5000 Vrms isolation voltage, 2A continuous output current, and 2.5A peak output capability. The device operates within a temperature range of -40°C to +125°C, ensuring reliability in demanding environments.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for enhanced durability
- High-speed signal transmission utilizing R²Coupler technology
- Rail-to-rail logic output configuration for direct interface compatibility
Applications
- IGBT gate drive circuits in automotive power electronics
- Motor control systems requiring high isolation
- Inverter and converter protection interfaces
Procurement Notes
Verify that the specific suffix matches the required automotive grade and packaging variant. Confirm compliance with relevant regional safety certifications such as UL, CSA, and IEC/EN/DIN EN 60747-5-5 before integration. Ensure thermal management aligns with the specified operating temperature range during system design.
Selection Notes
Select this component when high isolation voltage and automotive reliability are critical. The 6.8mm wide SOIC package facilitates robust creepage distances compared to standard variants. Consider the 2A continuous output current capacity for driving medium-power loads directly without additional buffering stages.
Part Context
This part belongs to the ACPL-K33T family, designed specifically for isolated gate driver applications. It distinguishes itself through automotive certification and extended temperature ratings, making it suitable for harsh operational conditions found in electric vehicle powertrains and industrial motor drives.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternative manufacturers or non-automotive equivalents.
