1N4468CUS

Single Zener Diodes Overview

The Microchip Technology 1N4468CUS is a surface mount Zener voltage regulator qualified to MIL-PRF-19500/406. It features a hermetically sealed void-less glass package with an internal metallurgical bond. The device provides a nominal Zener voltage of 13 V at a test current of 19 mA, with a maximum dynamic impedance of 8 Ohms and a maximum reverse leakage current of 0.05 µA at 10.4 V. It operates within a junction temperature range of -65°C to +175°C and dissipates up to 1.5 W.

Single Zener Diodes Feature Summary

• Hermetically sealed void-less glass construction with tungsten slugs for high reliability
• Internal Category 1 metallurgical bonds ensuring robust mechanical integrity
• Triple-layer passivation providing protection against environmental stressors
• Inherently radiation hard design suitable for demanding environments

Single Zener Diodes Applications

• High-reliability military applications where failure cannot be tolerated
• Voltage regulation over broad operating current and temperature ranges
• Circuits requiring inherent radiation hardness

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates a 2% tolerance level rather than the standard 5%. Confirm RoHS compliance status as commercial versions may differ from military grades. Ensure the ordering part number matches the required qualification level (JAN, JANTX, JANTXV, or JANS) per MIL-PRF-19500/406 specifications.

Single Zener Diodes Selection Notes

Select this component when a surface mount equivalent of the JEDEC registered 1N4468 series is required in a hermetic package. Consider the D-5A MELF form factor for space-constrained designs needing 1.5 W power dissipation. Verify that the 13 V breakdown voltage aligns with circuit requirements and check thermal derating curves for operation above 25°C ambient.

Single Zener Diodes Part Context

This device belongs to the 1N4460US through 1N4496US series of 1.5 Watt glass Zener diodes. These components serve as surface mount equivalents to popular axial-lead JEDEC registered series. The series offers extensive voltage selections from 3.3 to 200 Volts with various tolerance options available.
