CPT50060

Diode Arrays Overview

The CPT50060 is a Schottky PowerMod diode module manufactured by Microsemi Corporation. It features a 60 V repetitive peak reverse voltage rating and an average forward current of 250 A per package (125 A per leg). The device utilizes a common cathode configuration with baseplate mounting. Key electrical characteristics include a maximum instantaneous forward voltage of 0.73 V at 250 A and a typical junction capacitance of 8800 pF. Thermal performance specifies a maximum thermal resistance of 0.24°C/W per leg and 0.12°C/W per package.

Diode Arrays Procurement Notes

Verify the specific suffix requirement before ordering, as 'A' denotes Common Anode and 'D' denotes Doubler configurations. Confirm that the procurement matches the standard Common Cathode version unless otherwise specified. Ensure compliance with RoHS standards and check for any product change notifications or end-of-life status updates from the manufacturer prior to finalizing purchase orders.

Diode Arrays Selection Notes

Select this component for applications requiring high surge current handling and low conduction losses. The 175°C junction temperature capability allows for robust operation in demanding thermal environments. Consider the 0.12°C/W junction-to-case thermal resistance for heatsink sizing calculations. Verify that the 60V reverse voltage rating provides sufficient margin for the specific circuit operating conditions.

Diode Arrays Part Context

This part belongs to the Microsemi Schottky PowerMod series, designed for high-power discrete semiconductor applications. It is engineered to replace traditional silicon rectifiers where lower forward voltage and faster switching are required. The module format integrates multiple legs into a single baseplate-mounted unit to simplify assembly and improve thermal management in high-current power electronics systems.

Diode Arrays Replacement Considerations

Consult official Microsemi documentation for direct cross-reference data. Verify pinout compatibility and thermal resistance specifications when evaluating alternative modules. Ensure that substitute components meet or exceed the 250 A average forward current and 60 V reverse voltage ratings.

Diode Arrays FAQ

What is the difference between the standard CPT50060 and the CPT50060A?
