1N5819UR-1E3/TR

Overview

The Microchip Technology 1N5819UR-1E3/TR is a Schottky barrier rectifier housed in the DO-213AB (MELF) surface-mount package. It features a maximum repetitive reverse voltage of 45 V and an average forward current rating of 1 A. The device exhibits a typical 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 low forward voltage drop and minimal switching losses
Constructed with silicon material for high-frequency rectification applications
Designed in a glass-passivated MELF package for robust surface-mount integration

Applications

Low voltage, high frequency inverters
Free wheeling diodes in power circuits
Polarity protection systems
Small battery chargers

Procurement Notes

Verify that the specific suffix UR-1E3 corresponds to the commercial-grade variant in the DO-213AB package rather than the JAN military grade. Confirm RoHS compliance status as indicated by the E3 suffix. Ensure the MELF form factor matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount Schottky rectifier is required for 45 V applications. The 1 N average current rating suits moderate power loads. The wide operating temperature range supports demanding environments. Verify that the DO-213AB package dimensions align with the assembly constraints compared to axial alternatives.

Part Context

This part belongs to the 1N5819 series of power Schottky rectifiers manufactured by Microchip Technology. The series includes various packages such as DO-41 axial and DO-213AB MELF. The 1N5819UR-1E3/TR specifically denotes the tape-and-reel version of the commercial-grade unit in the MELF configuration.
