Overview
The Microchip Technology 1N5817E3/TR is a small-signal Schottky rectifier designed for through-hole mounting in the DO-41 package. It features a maximum repetitive reverse voltage of 20 V and an average forward current rating of 1 A. The device exhibits a low forward voltage drop, typically 1 V at rated current, with a maximum surge forward current capability of 50 A. Operating temperatures range from -65 °C to +125 °C junction temperature. This lead-free component utilizes silicon technology and is supplied in tape and reel packaging.
Feature Summary
- Low forward voltage drop characteristic for improved efficiency
- High surge current handling capability
- Lead-free construction compliant with environmental standards
Applications
- Power supply rectification
- Free-wheeling diodes in inductive circuits
- Reverse polarity protection
Procurement Notes
Verify the specific manufacturer source, as multiple vendors produce this standard part number. Confirm RoHS compliance status and lead-free designation (e3) matches project requirements. Check for obsolescence notices or lifecycle changes, particularly regarding onsemi variants which may be end-of-life. Ensure the tape and reel quantity aligns with assembly line needs.
Selection Notes
Select this component when a low-cost, high-reliability Schottky barrier rectifier is required for general-purpose applications. The 20 V rating suits low-voltage DC systems. Compare forward voltage specifications against alternatives if power loss is critical. Ensure the DO-41 through-hole footprint fits the PCB layout constraints.
Part Context
This part belongs to the standard 1N58xx series of Schottky rectifiers, widely used in consumer electronics and industrial equipment. Microchip Technology offers this variant with specific lead-free processing. The 'TR' suffix indicates tape and reel packaging for automated insertion.
Replacement Considerations
Direct substitutes include other manufacturers' 1N5817 parts such as those from onsemi or Taiwan Semiconductor. Verify pinout compatibility and thermal characteristics before substitution.
