CPT400100D

Diode Arrays Overview

The CPT400100D is a Schottky PowerMod rectifier module manufactured by Microsemi Corporation. It features a doubler configuration with a maximum repetitive peak reverse voltage of 100 V and an average forward current rating of 200 A per leg. The device utilizes a baseplate-mounted design with nickel-plated copper terminals. Key electrical characteristics include a maximum surge current of 400 A per leg, a typical junction capacitance of 4400 pF per leg, and a maximum thermal resistance from junction to case of 0.32°C/W.

Diode Arrays Feature Summary

• Schottky barrier technology for low forward voltage drop
• Guard ring protection structure
• Reverse energy tested construction
• Baseplate mounting with common cathode or doubler configurations

Diode Arrays Applications

• High frequency power conversion systems
• DC-DC converter modules
• Industrial power supplies
• Uninterruptible power supply (UPS) circuits

Diode Arrays Procurement Notes

Verify the specific suffix 'D' confirms the doubler configuration during procurement. Confirm RoHS compliance status as indicated in the datasheet documentation. Ensure mounting torque specifications are strictly followed to maintain thermal performance and mechanical integrity. Validate that the application environment remains within the specified operating junction temperature range of -55°C to 175°C.

Diode Arrays Selection Notes

Select this component when a doubler topology is required for high-current applications. The 100 V rating suits low-voltage DC distribution networks. Evaluate thermal management requirements against the 0.32°C/W junction-to-case resistance. Consider the 400 A surge capability for inrush current handling. Compare physical dimensions against available board space for baseplate mounting.

Diode Arrays Part Context

This part belongs to the CPT40080-CPT400100 series of Schottky PowerMod devices. The series offers varying reverse voltage ratings including 80 V, 90 V, and 100 V options. The 'D' suffix specifically denotes the doubler internal connection scheme, distinguishing it from common cathode ('C') or common anode ('A') variants within the same package family.

Diode Arrays Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Verify compatibility with industry equivalents such as MBR400100CT or 403CNQ100 based on pinout and electrical parameters. Ensure replacement parts match the doubler configuration and baseplate mounting style.
