1N5819UR-1

Overview

The Microchip Technology 1N5819UR-1 is a Schottky barrier rectifier featuring a 45 V repetitive peak reverse voltage and a 1 A average forward current. It utilizes a DO-213AB (MELF) surface-mount package with round-end termination. The device exhibits a maximum forward voltage of 490 mV at 1 A and a reverse leakage current of 50 µA at 45 V. It supports a peak non-repetitive forward surge current of 25 A and operates within a junction temperature range of -65°C to +125°C.

Feature Summary

Schottky barrier construction for low forward voltage drop and negligible switching losses
Military-grade qualification under MIL-PRF-19500/586 standards
DO-213AB MELF glass encapsulation for surface-mount reliability

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 JAN prefix indicates military qualification per MIL-PRF-19500/586. Confirm the UR-1 suffix corresponds to the specific reel tape packaging format. Ensure the DO-213AB MELF package dimensions match the target PCB footprint requirements. Check RoHS compliance status against specific project constraints.

Selection Notes

Select this component when a surface-mount Schottky rectifier with military reliability is required. The 45 V rating provides headroom above standard 40 V commercial variants. The MELF package offers robustness for harsh environments compared to standard SOD packages. Verify thermal management needs for the 1 A continuous current rating in the final assembly.

Part Context

This part belongs to the 1N5819 series of axial and surface-mount Schottky rectifiers manufactured by Microchip Technology. It serves as a ruggedized, qualified alternative to commercial equivalents, maintaining the core electrical characteristics while adhering to strict military quality control processes and traceability requirements.
