Overview
The Microchip Technology 1N5821 is a silicon Schottky barrier rectifier designed for general-purpose applications. It features a maximum average forward rectified current of 3 A and a maximum repetitive peak reverse voltage of 30 V. The device utilizes a DO-201AD axial leaded package, suitable for through-hole mounting. Key electrical characteristics include a low forward voltage drop and high switching efficiency, making it appropriate for power supply circuits requiring fast recovery and minimal power loss.
Feature Summary
- Schottky barrier technology ensures low forward voltage drop and high switching efficiency
- Robust construction supports high current surge capability
- Hermetically sealed design guarantees reliability under extreme temperature conditions
Applications
- General-purpose rectification in power supply circuits
- Free-wheeling diode applications in inductive loads
- DC-AC conversion systems requiring fast recovery
Procurement Notes
Verify the specific manufacturer source when sourcing this component, as multiple vendors produce the 1N5821 designation. Confirm that the received unit matches the required DO-201AD package and electrical ratings. Check for compliance with relevant environmental standards if applicable to your system requirements. Ensure proper handling procedures are followed during installation.
Selection Notes
Select the 1N5821 for designs prioritizing low forward voltage and high efficiency over higher voltage blocking capabilities. Consider the 3 A current rating and 30 V reverse voltage limits when sizing components for thermal management. Evaluate the through-hole package constraints against available PCB real estate and mechanical mounting requirements.
Part Context
This component belongs to the standard 1N582x series of Schottky rectifiers, which includes variants with different voltage ratings such as the 1N5820 (20 V) and 1N5822 (40 V). These devices share similar physical dimensions and current handling capabilities but differ in their maximum reverse voltage specifications. The series is widely recognized for its reliability in medium-power rectification tasks.
Replacement Considerations
Compatible substitutes include the 1N5821 from other manufacturers like Vishay or Taiwan Semiconductor, provided they meet the same 3 A / 30 V specifications and DO-201AD package form factor. Verify pinout compatibility and thermal performance before substitution.
