UPS5819E3/TR13

Single Diodes Overview

The UPS5819E3/TR13 is a single Schottky barrier rectifier manufactured by Microchip Technology, housed in the PowerMITE-1 (DO-216AA) surface-mount package. It features a metallic bottom tab for efficient heat dissipation and low thermal resistance. Key electrical parameters include a peak repetitive reverse voltage of 20 V, an average rectified forward output current of 1.0 A at 135°C case temperature, and a maximum forward voltage drop of 0.45 V at 1.0 A. The device supports a non-repetitive peak forward surge current of 50 A and operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Low forward voltage drop for improved efficiency
• Integral locking bottom metal tab acts as an efficient heat path from die to mounting plane
• Full metallic bottom eliminates possibility of solder flux entrapment during assembly

Single Diodes Applications

• Switching power supplies
• Regulating power supplies
• Charge pump circuits

Single Diodes Procurement Notes

Verify that the ordering suffix TR13 corresponds to the 13-inch tape and reel packaging with a base quantity of 12,000 units. Confirm the component is RoHS compliant and meets UL94V-0 epoxy standards. Ensure the specific part number matches the required 20V rating and DO-216AA package dimensions before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a low-profile surface-mount Schottky rectifier with high thermal performance is required. The PowerMITE-1 package provides superior heat sinking capabilities compared to standard plastic packages. Consider the 20V reverse voltage rating and 1A current capacity to ensure adequate margins for the target switching or regulating power supply application.

Single Diodes Part Context

This component belongs to the UPS58xx series of Schottky barrier rectifiers produced by Microchip Technology. The 'e3' designation indicates lead-free construction, while 'TR13' specifies the 13-inch tape and reel delivery format. The series is designed for applications requiring low forward voltage and efficient thermal management in compact surface-mount layouts.

Single Diodes Replacement Considerations

The datasheet references the UPS5817e3 as a related product variant sharing identical mechanical and electrical characteristics. Verify pinout compatibility and exact voltage ratings when substituting with other members of the UPS58xx family or equivalent DO-216AA packaged Schottky diodes.
