ACPL-P456-000E

Overview

The ACPL-P456-000E is a high common-mode transient immunity (CMTI) intelligent power module and gate drive interface optocoupler manufactured by Broadcom Limited. It features a single channel with DC input and open collector, Schottky clamped logic output. The device supports data rates up to 1 MBd and provides an isolation voltage of 3750 Vrms. Key electrical parameters include a minimum CMTI of 15 kV/µs, a maximum forward current of 25 mA, and an operating temperature range from -40°C to 100°C.

Feature Summary

• High common-mode transient immunity for reliable operation in noisy environments
• Schottky-clamped open collector output for fast switching performance
• Integrated design suitable for driving intelligent power modules

Applications

• Intelligent Power Module (IPM) interfaces
• Gate drive circuits for motor drives
• Switching power supply control loops

Procurement Notes

Verify the specific suffix code against official Broadcom documentation to confirm pinout and functional variations. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Confirm package type matches the required PCB footprint before ordering.

Selection Notes

Select this component when high CMTI is critical for system stability in high-voltage switching applications. The open collector output requires appropriate pull-up resistor configuration. Verify that the input current limits are respected within the specified operating temperature range. Consider thermal management requirements for the surrounding circuitry during continuous operation.

Part Context

This device belongs to the ACPL-P45x series of high-speed optocouplers designed for industrial and automotive applications. It complements other variants like the ACPL-P454 by offering specialized output structures for gate drive interfacing. The series emphasizes robust isolation capabilities and signal integrity in electrically noisy environments.

Replacement Considerations

Check for direct substitutes such as the ACPL-P456-520E for potential packaging or minor specification differences. Verify compatibility with existing gate driver circuits before swapping components. Ensure replacement parts meet the same CMTI and isolation voltage standards.
