JAN1N3026C-1

Single Zener Diodes Overview

The JAN1N3026C-1 is a 1-watt glass case Zener diode qualified per MIL-PRF-19500/115. It features a hermetically sealed DO-41 package with tungsten slugs and metallurgically bonded construction. The nominal Zener voltage is 18 volts, measured at a test current of 14 mA. It offers a tight voltage tolerance of 2%, indicated by the 'C' suffix. Maximum reverse leakage current is specified at 10 µA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-41 package for high-reliability environments
• Metallurgically bonded double plug construction
• Qualified to JAN, JANTX, and JANTXV military standards

Single Zener Diodes Applications

• Voltage regulation over broad operating temperature ranges
• High-reliability electronic circuits requiring radiation hardness
• Precision reference applications utilizing low leakage characteristics

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required reliability level (JAN) and voltage tolerance (C for 2%). Confirm RoHS compliance status if applicable, as standard JAN versions may not be compliant. Ensure the package type corresponds to the design requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 18 V Zener voltage with 2% precision is required in a through-hole glass package. Consider the 1 W power dissipation limit and thermal derating curves for high-temperature operation. Verify compatibility with existing circuit layouts designed for the DO-41 footprint.

Single Zener Diodes Part Context

This part belongs to the established 1N3016B-1 through 1N3045B-1 series manufactured by Microchip Technology. The series provides a wide range of Zener voltages from 6.8 V to 110 V in the same glass DO-41 package format, ensuring consistent mechanical integration across different voltage requirements.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N3026B-1 (5% tolerance) or JAN1N3026D-1 (1% tolerance). Surface mount alternatives are available in the DO-213AB package, such as JAN1N3026BUR-1.
