1N5065

Single Zener Diodes Overview

The Microchip Technology 1N5065 is a fused-in-glass, metallurgically bonded 3-watt Zener diode designed for high-power voltage regulation. It features an 8.2V nominal Zener voltage with a tight 5% tolerance and operates within a temperature range of -65°C to +175°C. The device utilizes a hermetically sealed glass axial package, providing superior surge current handling capabilities compared to conventional 1-watt types.

Single Zener Diodes Feature Summary

• Hermetically sealed in glass for environmental protection
• Metallurgically bonded fused-in-glass construction
• High surge rating exceeding conventional 1-watt types by ten times

Single Zener Diodes Applications

• High-reliability voltage regulation circuits
• Military and aerospace power supplies
• Harsh environment electronic systems

Single Zener Diodes Procurement Notes

Verify the manufacturer origin carefully, as SSDI also produces the SZN5065ATX variant which shares similar electrical specifications but differs in packaging and official part numbering. Confirm that the specific unit acquired is the Microchip Technology 1N5065 and not a generic equivalent or alternative manufacturer's version to ensure compliance with required military or space-grade standards.

Single Zener Diodes Selection Notes

Select this component when a robust 3-watt Zener diode with strict voltage tolerance is required for critical applications. The fused-in-glass technology offers enhanced durability against thermal shock and mechanical stress compared to standard epoxy packages. Ensure the design accounts for the physical size constraints of the axial glass leaded package.

Single Zener Diodes Part Context

This component belongs to the series of high-power Zener diodes manufactured by Microchip Technology (formerly Microsemi). These devices are engineered for demanding environments where reliability is paramount. The 1N5065 specifically addresses the need for stable voltage reference and regulation in systems requiring higher power dissipation than standard small-signal diodes can provide.

Single Zener Diodes Replacement Considerations

Public confirmed substitute part numbers include the Digitron Semiconductors 1N5065 and the SSDI SZN5065ATX. Verify that any replacement matches the 3W power rating, 8.2V Zener voltage, and 5% tolerance requirements.
