1N5819UR-1/TR

Overview

The JAN1N5819UR-1/TR is a surface-mount Schottky barrier rectifier manufactured by Microchip Technology. It features a DO-213AB (MELF) glass package and provides an average forward current of 1 A with a maximum repetitive reverse voltage of 45 V. The device exhibits a low forward voltage drop of 490 mV at 1 A and a maximum reverse leakage current of 50 µA at 45 V. It supports a forward surge current of 25 A and operates within a junction temperature range of -65°C to +125°C.

Feature Summary

Utilizes Schottky barrier technology for extremely fast switching and negligible switching losses.
Features very small conduction losses due to low forward voltage drop characteristics.
Constructed in a hermetically sealed glass MELF package suitable for harsh environments.

Applications

Switch Mode Power Supplies
High frequency DC to DC converters
Low voltage high frequency inverters
Free wheeling applications
Polarity protection circuits

Procurement Notes

Verify the specific ordering suffix UR-1/TR against the manufacturer's datasheet to confirm the tape-and-reel packaging format and MIL-PRF-19500/586 qualification level. Ensure compatibility with automated surface-mount assembly processes given the MELF form factor. Cross-reference the RoHS status, as military variants often differ from commercial standards.

Selection Notes

Select this component when a hermetically sealed, high-reliability Schottky rectifier is required for space-constrained designs. The DO-213AB package offers a compact footprint compared to axial leads while maintaining robust thermal performance. Consider the 45 V rating for low-voltage power paths where standard silicon rectifiers would incur excessive forward voltage loss.

Part Context

This part belongs to the 1N5819 series of 1 Amp Schottky Barrier Rectifiers. It shares core electrical specifications with the through-hole JAN1N5819-1 but utilizes a surface-mount MELF package. The product line includes various qualification levels such as JAN, JANTX, and JANTXV, all adhering to the MIL-PRF-19500/586 standard for military-grade reliability.
