1N4465

Single Zener Diodes Overview

The Microchip Technology 1N4465 is a 1.5 W glass Zener diode with a nominal voltage of 10 V and ±5% tolerance. It operates within a junction temperature range of -65°C to +175°C. Key electrical parameters include a maximum dynamic impedance of 5 Ohms at the test current, a maximum reverse leakage current of 300 nA at 8 V, and a forward voltage of 1.5 V at 1 A. The device utilizes a DO-204AL (DO-41) axial lead package.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction with internal metallurgical bonds for high reliability.
• Qualified per MIL-PRF-19500/406 for military applications requiring failure-free operation.
• Inherently radiation hard and non-sensitive to electrostatic discharge.

Single Zener Diodes Applications

• High-reliability voltage regulation in aerospace systems
• Military-grade circuit protection
• Harsh environment power supply design

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level (JAN, JANTX, JANTXV, or JANS). Confirm RoHS compliance status if environmental regulations apply, as commercial versions differ from military grades. Ensure the package type aligns with the intended through-hole mounting requirements.

Single Zener Diodes Selection Notes

Select this component for applications demanding robust performance under extreme thermal conditions up to 175°C. The 1.5 W power rating supports steady-state dissipation at elevated temperatures when mounted correctly. Verify that the 10 V breakdown voltage meets the specific reference needs of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N4460–1N4496 series of industry-recognized Zener voltage regulators. The series provides a wide selection of voltages ranging from 3.3 V to 200 V. All devices share the same hermetically sealed glass package and are designed for consistent performance across broad operating currents.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 1N4465 variants with different qualification suffixes such as JAN1N4465, JANTX1N4465, or JANTXV1N4465. These parts maintain identical electrical characteristics but offer varying levels of military reliability certification.
