1N4467

Single Zener Diodes Overview

The Microchip Technology 1N4467 is a 12 V Zener voltage regulator with a 1.5 W steady-state power dissipation rating and ±5% nominal tolerance. It operates within a junction temperature range of -65 °C to +175 °C, featuring a maximum dynamic impedance of 7 Ω at a test current of 21 mA. The device utilizes a voidless hermetically sealed glass package with an internal metallurgical bond and flexible axial-lead terminals.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction with internal metallurgical bonding for robust reliability
• Military qualification available per MIL-PRF-19500/406 across JAN, JANTX, JANTXV, and JANS levels
• Inherently radiation hard and non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• High-reliability voltage regulation where failure cannot be tolerated
• Broad operating current and temperature range stabilization
• Radiation-hardened electronic circuit design

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm the required reliability level (JAN, JANTX, JANTXV, or JANS) and RoHS compliance status. Commercial versions are available in RoHS-compliant matte tin finishes, while military grades utilize tin/lead terminations. Confirm package availability in standard DO-41 axial lead or surface mount configurations as needed for the assembly process.

Single Zener Diodes Selection Notes

Select this component for applications requiring high thermal stability and robust physical construction. The 1.5 W power rating supports significant current handling, while the wide operating temperature range ensures functionality in extreme environments. Ensure the selected tolerance variant meets the precision requirements of the target voltage regulation circuit.

Single Zener Diodes Part Context

This part belongs to the industry-recognized 1N4460–1N4496 series of 1.5 W glass Zener diodes. The series provides extensive voltage selections from 3.3 V to 200 V with standard 5% tolerances. It is designed for both commercial and demanding military-grade applications requiring long-term operational stability.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N4467 variants with different suffixes indicating specific military qualification levels or RoHS compliance. Surface mount equivalents within the same series include the 1N4467US configuration.
