APT40DS10HJ is listed in the Bridge Rectifier range at ChipApex. The manufacturer field lists Microsemi Corporation. Its product description is BRIDGE RECT 1P 100V 40A SOT-227. Review the specifications below when checking this part for your BOM.
The APT40DS10HJ is an ISOTOP Schottky Diode Full Bridge Power Module manufactured by Microsemi. It features a maximum DC reverse voltage of 100 V and supports a forward current of 40 A at a case temperature of 80°C. The device operates within a junction temperature range of -55°C to 150°C, with a maximum non-repetitive forward surge current of 450 A. It utilizes the SOT-227 package, providing an RMS isolation voltage of 2500 V between any terminal and the case.
Verify component authenticity through authorized Microsemi distributors or official channels. Confirm RoHS compliance status for specific manufacturing lots. Ensure proper electrostatic discharge handling procedures are followed during storage and installation. Validate thermal management requirements against the specified junction-to-case resistance values before deployment.
Select this module for applications requiring high-frequency operation and low switching noise. Evaluate thermal constraints based on the 1.1 °C/W junction-to-case resistance. Consider the isolated package design for direct heatsink mounting. Verify that system voltage does not exceed the 100 V peak repetitive reverse rating under all operating conditions.
This component belongs to the Microsemi ISOTOP series of full bridge power modules. It integrates multiple Schottky diodes into a single unit to minimize stray inductance. The SOT-227 package provides a compact solution for high-current applications while maintaining electrical isolation from the mounting surface.
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Microsemi ISOTOP series modules only if electrical ratings match exactly.
