UPS540E3/TR13

Single Diodes Overview

The UPS540E3/TR13 is a 5 A Schottky Barrier Rectifier manufactured by Microchip Technology, housed in the PowerMITE-3 surface-mount package. It features a peak repetitive reverse voltage of 40 V and an average rectified output current of 5 A. The device exhibits a low forward voltage of 0.47 V at 5 A and 25°C, with a maximum non-repetitive peak forward surge current of 100 A. Thermal resistance from junction to case is 3.2 °C/Watt, supporting high-efficiency operation in switching power supplies.

Single Diodes Feature Summary

• PowerMITE-3 package includes a full metallic bottom to eliminate solder flux entrapment during assembly
• Integral locking tab acts as an efficient heat path for heat-sink mounting
• Guard-ring-die construction provides transient protection
• Low profile design compatible with automatic insertion equipment

Single Diodes Applications

• Switching and regulating power supplies
• Charge pump circuits
• Silicon Schottky rectification for minimal reverse voltage recovery

Single Diodes Procurement Notes

Verify the component matches the specified 5 A rating and 40 V reverse voltage requirements. Confirm the PowerMITE-3 package dimensions align with the PCB footprint layout. Ensure the RoHS compliant e3 suffix is required for environmental standards. Check thermal management needs against the 3.2 °C/W junction-to-case resistance specification.

Single Diodes Selection Notes

Select this component for applications requiring high-frequency operation and minimal reverse recovery oscillations. The low forward voltage reduces conduction losses compared to standard rectifiers. Consider the small footprint and efficient heat dissipation provided by the metallic bottom tab for compact designs.

Single Diodes Part Context

This part belongs to the UPS series of Schottky barrier rectifiers designed for high efficiency. The e3 suffix indicates lead-free (RoHS) compliance. The TR13 designation specifies the tape and reel packaging format, suitable for automated surface-mount assembly processes.

Single Diodes Replacement Considerations

Consult official substitution lists for equivalent 5 A Schottky rectifiers in similar packages. Verify that any replacement maintains the 40 V reverse voltage rating and comparable thermal characteristics.
