UPS5100HE3

Single Diodes Overview

The UPS5100HE3 is a Schottky barrier rectifier manufactured by Microsemi Corporation. It features a 100V repetitive peak reverse voltage and a 5A average forward rectified current rating. The device utilizes the PowerMite 3 package, designed for through-hole mounting. This component is engineered to provide high-efficiency rectification with low forward voltage drop and minimal reverse leakage current, suitable for general-purpose power supply applications.

Single Diodes Feature Summary

• Schottky barrier technology ensures fast switching speeds and low forward voltage drop
• PowerMite 3 package provides robust mechanical stability for through-hole assembly
• High surge current capability protects against transient overload conditions

Single Diodes Applications

• General-purpose rectification in AC/DC power supplies
• Free-wheeling diodes in DC-DC converters
• Polarity protection circuits in electronic systems

Single Diodes Procurement Notes

Verify the manufacturer designation as Microsemi Corporation or its successor entity, Microchip Technology, depending on the production era. Confirm the specific suffix HE3 indicates RoHS compliance and halogen-free construction. Ensure the package type matches the required through-hole footprint for your PCB design. Cross-reference the datasheet revision to confirm electrical characteristics align with your system requirements.

Single Diodes Selection Notes

Select this component when a low forward voltage drop is critical for efficiency in low-voltage, high-current applications. The 100V rating provides sufficient margin for standard 12V or 24V systems. Consider the thermal management capabilities of the PowerMite 3 package if operating near the maximum current limit. Verify that the switching speed meets the frequency requirements of the target circuit topology.

Single Diodes Part Context

This part belongs to the PowerMite series of rectifiers, which are characterized by their rugged glass-passivated silicon junctions. The series is designed for high-reliability applications requiring efficient power conversion. The HE3 suffix typically denotes environmental compliance, distinguishing it from older non-compliant variants within the same electrical specification family.

Single Diodes Replacement Considerations

Direct replacements must match the 100V, 5A specifications and the PowerMite 3 package. Check for equivalent Schottky rectifiers from other manufacturers that offer similar forward voltage and surge current ratings. Ensure any substitute maintains the same pinout and thermal dissipation characteristics.
