1N4467/TR

Single Zener Diodes Overview

The Microchip Technology 1N4467/TR is a Zener voltage regulator diode with a nominal breakdown voltage of 12.0 V and a maximum dynamic impedance of 7 Ohms at the test current of 21 mA. It features a standard tolerance of ±5% and supports a maximum continuous current of 119 mA, dissipating up to 1.5 W of steady-state power. The device operates within a junction temperature range of -65°C to +175°C and includes a maximum reverse leakage current of 0.25 µA at 9.6 V.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction utilizing internal metallurgical bonds for robust reliability.
• Qualified per MIL-PRF-19500/406 standards for high-reliability applications where failure cannot be tolerated.
• Inherently radiation hard as described in Microsemi MicroNote 050.
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 method 1020.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges.
• High-reliability military and aerospace electronic systems.
• Circuits requiring inherent radiation hardness.

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level, such as JAN, JANTX, JANTXV, or JANS, as these determine the manufacturing lot traceability and testing rigor. Confirm whether RoHS compliance is necessary, noting that compliant versions are available on commercial grade only. Ensure the package type aligns with the design requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 12 V reference is needed with tight tolerance options available via suffix codes. Consider the 1.5 W power dissipation limit and thermal resistance characteristics for heat management. Verify that the axial-lead mounting terminals fit the board layout constraints. Evaluate the surge current capability against potential transient events in the circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N4460–1N4496 series of industry-recognized 1.5 watt Zener voltage regulators. The series offers extensive selections from 3.3 to 200 volts with standard 5% tolerance. Tighter tolerances of 1% and 2% are also available through specific ordering suffixes. The series is designed for flexible axial-lead mounting.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N4467CUS/TR and 1N4467US. Verify that replacement devices maintain the same hermetic sealing and MIL-PRF-19500/406 qualification if military-grade reliability is required.
