1N4467US/TR

Single Zener Diodes Overview

The Microchip Technology 1N4467US/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 12.0 V and a standard tolerance of ±5%. It operates within a junction temperature range of -65°C to +175°C and dissipates up to 1.5 W at 25°C ambient. The device features a voidless hermetically sealed glass package with an internal metallurgical bond, providing robust construction suitable for high-reliability applications.

Single Zener Diodes Feature Summary

• Hermetically sealed void-less glass construction with internal metallurgical bonding
• Triple-layer passivation for enhanced durability
• Inherently radiation hard design
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• High-reliability voltage regulation where failure cannot be tolerated
• Military qualified electronic systems
• Broad operating current and temperature range stabilization

Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for your application, as the base part number covers multiple qualification tiers. Confirm RoHS compliance status if environmental regulations apply, noting that compliant versions are available on commercial grade only. Ensure the tape and reel packaging meets EIA-481-B standards for your assembly line.

Single Zener Diodes Selection Notes

Select this component when a 12.0 V reference is needed in a surface mount form factor. Consider the thermal impedance characteristics for transient conditions and verify the maximum continuous current rating against your circuit load. The wide operating temperature range supports deployment in extreme environments without derating adjustments below 25°C.

Single Zener Diodes Part Context

This device belongs to the 1N4460US through 1N4496US series of 1.5-watt glass Zener diodes. These regulators are industry-recognized equivalents to popular JEDEC registered axial-lead series but adapted for surface mount integration. The series offers extensive voltage selections from 3.3 to 200 volts with various tolerance options.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N4467 variants such as 1N4467D or JAN1N4467CUS/TR, provided they match the required military qualification level and package type. Verify that substitute parts maintain the same 12.0 V nominal voltage and 1.5 W power dissipation rating.
