UPS140/TR7

Single Diodes Overview

The UPS140/TR7 is a surface-mount Schottky rectifier manufactured by Microchip Technology, housed in the Powermite package (JEDEC DO-216AA). It features a maximum height of 1.1 mm and a footprint area of 8.45 mm². The device supports a peak repetitive reverse voltage of 40 V and an average rectified forward current of 1.0 A at a case temperature of 135°C. It offers low thermal resistance with a direct thermal path via the exposed cathode heat sink.

Single Diodes Feature Summary

• Patented heat sink design provides SMA-level thermal performance within a significantly smaller footprint
• Low forward voltage characteristics optimize efficiency and extend battery life in portable applications
• Exposed cathode structure enables direct thermal dissipation to the PCB

Single Diodes Applications

• Reverse battery protection circuits
• AC/DC and DC/DC converters
• O-ring configuration for multiple supply voltages
• Battery-powered portable products such as cellular phones and PDAs

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The standard datasheet indicates a 12 mm tape and reel format containing 12,000 units per reel. Confirm that the TR7 designation aligns with this reel specification before procurement to ensure compatibility with automated assembly equipment.

Single Diodes Selection Notes

Select this component when space constraints require a compact surface-mount solution without compromising thermal management. The Powermite package allows for high-efficiency rectification in tight footprints. Ensure the application operates within the specified junction temperature range and accounts for the low forward voltage drop to maximize system power efficiency.

Single Diodes Part Context

This part belongs to the UPS140 series of 1A Schottky rectifiers from Microchip Technology. It utilizes the proprietary Powermite package, which is registered under JEDEC DO-216AA standards. The series is engineered specifically for high-efficiency power conversion in portable electronics where physical size and thermal performance are critical design factors.

Single Diodes Replacement Considerations

Direct substitutes include the UFS140Je3/TR13 for ultrafast recovery requirements or the USBQNM50403CE3/TR7 for ESD protection arrays. Verify pinout compatibility and thermal resistance ratings when considering alternative packages.
