1N5814

Overview

The Microchip Technology 1N5814 is a high-reliability ultra-fast recovery rectifier designed for demanding applications. It features a maximum repetitive reverse voltage of 50 to 150 volts and an average forward current rating of 20 amperes. The component utilizes voidless-glass construction for hermetic sealing, ensuring robust performance in high-voltage environments where failure is not an option.

Feature Summary

• Ultra-fast recovery rectifier technology
• Hermetically sealed with voidless-glass construction
• High-reliability design for critical systems

Applications

• High-voltage power supplies
• Military-grade electronic systems
• High-reliability industrial equipment

Procurement Notes

Verify the specific voltage sub-rating (50V, 75V, 100V, or 150V) required for your application, as the 1N5814 designation covers a range within this family. Confirm that the hermetic package and ultra-fast recovery characteristics align with your circuit's thermal and switching requirements before finalizing procurement.

Selection Notes

Select this component when ultra-fast recovery times and high reliability are prioritized over standard Schottky or fast-recovery alternatives. Ensure the system can accommodate the through-hole DO-41 package and the specific thermal management needs associated with a 20A current rating in a hermetic enclosure.

Part Context

This part belongs to the 1N58xx series of high-reliability rectifiers manufactured by Microchip Technology. It is distinct from the common 1N581x Schottky diode series due to its ultra-fast recovery nature and higher current handling capabilities, targeting specialized high-voltage and military applications rather than general-purpose low-voltage rectification.
