Overview
The Microchip Technology 1N5822US/TR is a small-signal Schottky rectifier designed for surface-mount applications. It features a maximum repetitive peak reverse voltage of 40V and an average forward rectified current of 3A. The device utilizes a Square MELF (SQ-MELF-2) package configuration. Key electrical characteristics include a typical forward voltage drop of 0.525V at 3A and a maximum reverse leakage current of 2mA at 40V. It supports a peak forward surge current of 80A and operates within a junction temperature range of -65°C to +125°C.
Feature Summary
- Schottky barrier technology enables very low conduction losses and negligible switching losses.
- Extremely fast switching capability suitable for high-frequency inverters and DC-to-DC converters.
- Square MELF package provides a compact form factor for surface-mount assembly.
Applications
- Switch Mode Power Supplies (SMPS)
- High frequency DC to DC converters
- Free wheeling diodes in low voltage circuits
- Polarity protection circuits
- Small battery chargers
Procurement Notes
Verify the specific manufacturer part number against official Microchip Technology documentation to confirm the SQ-MELF-2 package and tape-and-reel delivery format. Ensure that the component meets all required environmental standards and RoHS compliance specifications for the intended application before procurement.
Selection Notes
Select this component for designs requiring a robust surface-mount Schottky rectifier with high current handling capabilities. The 40V rating and 3A continuous current make it suitable for low-voltage power systems. Consider the thermal performance and package size constraints when integrating into the circuit layout.
Part Context
This component belongs to the 1N58xx series of Schottky rectifiers, widely recognized for their efficiency in power conversion applications. The US suffix typically denotes a specific surface-mount variant, while the /TR indicates tape-and-reel packaging for automated assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with direct replacements by comparing electrical parameters such as VRRM, Io, and Vf, ensuring the alternative matches the SQ-MELF-2 package dimensions.
