1N4467US

Single Zener Diodes Overview

The Microchip Technology 1N4467US is a surface mount Zener voltage regulator with a nominal breakdown voltage of 12 V. It features a maximum power dissipation of 1.5 W and a standard tolerance of ±5%. The device operates within a junction temperature range of -65°C to +175°C. Electrical characteristics include a maximum dynamic impedance of 7 Ohms at a test current of 21 mA, a maximum reverse leakage current of 0.3 µA at 9.6 V, and a forward voltage of 1.5 V at 1 A.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass package with internal metallurgical bonds for robust construction.
• Military qualified per MIL-PRF-19500/406 for high-reliability applications.
• Inherently radiation hard and non-sensitive to electrostatic discharge.

Single Zener Diodes Applications

• Voltage regulation in broad operating current and temperature ranges.
• High-reliability electronic systems where component failure cannot be tolerated.
• Radiation-hardened circuit designs.

Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for the application, as qualification levels vary. Confirm RoHS compliance status, noting that compliant versions are available only on commercial grade parts. Ensure the ordering suffix matches the desired tolerance and termination finish specifications.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 12 V reference with a 1.5 W power rating in a surface mount form factor. Consider the 7 Ohm dynamic impedance for stability requirements. Verify thermal management capabilities against the specified junction-to-end cap thermal resistance and derating curves for ambient temperatures exceeding 25°C.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of industry-recognized 1.5 watt Zener voltage regulators. The series offers selections from 3.3 to 200 volts with standard 5% tolerance, alongside tighter 1% and 2% options. These devices serve as surface mount equivalents to popular JEDEC registered axial-lead series.

Single Zener Diodes Replacement Considerations

Direct replacements include other variants within the 1N4460US–1N4496US series or the equivalent axial-lead 1N4460–1N4496 series. Cross-reference specific reliability qualifications such as JAN, JANTX, JANTXV, or JANS when substituting military-grade components.
