DST30100C

Diode Arrays Overview

The Littelfuse DST30100C is a dual Schottky barrier rectifier featuring a common cathode configuration housed in a TO-220AB package. It provides a total average forward current of 30A, distributed as 15A per leg at a case temperature of 115°C. The device supports a peak repetitive reverse voltage of 100V and withstands a non-repetitive surge current of 200A per leg. Junction temperatures range from -55°C to +150°C with a thermal resistance of 2.5°C/W per leg.

Diode Arrays Feature Summary

• Ultra-low forward voltage drop for improved efficiency
• High junction temperature capability up to 150°C
• Guard ring structure for enhanced ruggedness and reliability

Diode Arrays Applications

• Switching mode power supplies
• DC/DC converters
• Free-wheeling diodes
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific package variant against the datasheet pinout diagrams, as the DST series includes D2PAK, ITO-220AB, and TO-220AC options alongside the standard TO-220AB. Confirm that the ordering suffix matches the required configuration and packing mode, such as tubes or reels, to ensure compatibility with assembly processes.

Diode Arrays Selection Notes

Select this component for high-frequency applications requiring low leakage and minimal forward voltage loss. Ensure the thermal design accommodates the 2.5°C/W junction-to-case resistance. Verify that the operating current does not exceed the 15A per leg rating under the specified case temperature conditions to maintain device integrity.

Diode Arrays Part Context

This part belongs to the Littelfuse DST series of ultra-low VF Schottky Barrier Rectifiers. Designed for commercial and industrial use, the series emphasizes high temperature performance and low leakage characteristics suitable for demanding power conversion environments.
