JANS1N6341

Single Zener Diodes Overview

The JANS1N6341 is a military-qualified Zener voltage regulator diode manufactured by Microchip Technology. It belongs to the industry-recognized 1N6309 through 1N6355 series, featuring a 0.5-watt power rating and voidless hermetically sealed glass construction with internal metallurgical bonds. This component serves as the surface mount equivalent for the axial-leaded JEDEC registered 1N63xx series, utilizing a B-SQ MELF package. It provides stable voltage regulation suitable for high-reliability applications where failure is not an option.

Single Zener Diodes Feature Summary

• Military qualification per MIL-PRF-19500/533 standards
• Hermetically sealed voidless-glass package
• Internal metallurgical bonding for enhanced reliability

Single Zener Diodes Applications

• High-reliability aerospace systems
• Military electronic circuits
• Critical voltage regulation in defense equipment

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required tolerance level (1%, 2%, or 5%) and voltage rating from the official datasheet. Confirm the presence of Category I or Category III metallurgical bonds if specified for the application. Ensure the procurement documentation includes full traceability records and compliance with MIL-PRF-19500/533 requirements for military-grade components.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for applications previously using axial-leaded 1N63xx diodes. The choice depends on the need for hermetic sealing and military qualification. Consider the available voltage range from 2.4 to 200 volts and the specific tolerance requirements. The B-SQ package must fit the designated footprint while maintaining the necessary thermal and electrical performance characteristics.

Single Zener Diodes Part Context

This device is part of the broader 1N6309 through 1N6355 family of Zener diodes offered by Microchip. While commercial versions exist under JAN, JANTX, and JANTXV designations, the JANS suffix denotes the highest level of radiation hardness and reliability. It complements other surface-mount and through-hole options provided by the manufacturer for various power ratings and package types.

Single Zener Diodes Replacement Considerations

Direct replacements include other JANS1N6341 units from authorized distributors. Cross-reference with JAN1N6341US or JANTX1N6341US only if military qualification and radiation hardness are not strictly required. Verify pinout compatibility and package dimensions against the existing PCB layout before substitution.
