DST3060LC

Diode Arrays Overview

The Littelfuse DST3060LC is a dual Schottky barrier rectifier in a TO-220AB common cathode package. It provides a total average forward current of 30 A (15 A per leg) at a case temperature of 105°C and withstands a peak repetitive reverse voltage of 60 V. The device features a maximum junction temperature of 125°C, with a thermal resistance of 5.0 °C/W per leg. Forward voltage drop ranges from 0.43 V to 0.55 V depending on current and temperature.

Diode Arrays Feature Summary

• Ultra-low forward voltage drop reduces conduction losses
• High junction temperature capability ensures reliability
• Guard ring design enhances ruggedness and long-term stability

Diode Arrays Applications

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

Diode Arrays Procurement Notes

Verify the specific package variant against the datasheet pinout diagrams, as the TO-220AB configuration supports multiple internal arrangements. Confirm that the required thermal management aligns with the specified 5.0 °C/W junction-to-case resistance for continuous operation. Ensure the application voltage does not exceed the 60 V rating under all operating conditions.

Diode Arrays Selection Notes

Select this component when low forward voltage drop is critical for system efficiency. The common cathode topology allows for use in bridge or synchronous rectification circuits. Verify that the 125°C maximum junction temperature meets the ambient requirements of the enclosure. Consider the 170 A surge current capability for transient protection needs.

Diode Arrays Part Context

This device belongs to the DST series of ultra-low voltage Schottky barrier rectifiers designed for commercial and industrial applications. The series offers superior performance compared to traditional silicon switching diodes, specifically regarding leakage current and forward voltage characteristics. It is part of Littelfuse's broader portfolio of power semiconductors optimized for high-frequency switching environments.

Diode Arrays Replacement Considerations

Check for direct substitutes within the DST series offering identical 60V ratings and 30A total current capacity. Verify that alternative components maintain the same TO-220AB footprint and pinout compatibility to ensure seamless integration without PCB redesign.
