JANTXV1N6346DUS

Single Zener Diodes Overview

The JANTXV1N6346DUS is a Zener diode voltage regulator manufactured by Microchip. It features an 82 V nominal Zener voltage with a test current of 1.5 mA and a dynamic impedance of 220 Ohms. The component utilizes a B-SQ-MELF-2 surface-mount package and supports a power dissipation of 500 mW. It operates within a temperature range of -65 °C to +175 °C, offering high-reliability performance for demanding environments.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless-glass construction ensuring long-term reliability
• Internal metallurgical bonds for enhanced structural integrity
• Surface-mount equivalent of the JEDEC registered 1N6309 through 1N6355 series

Single Zener Diodes Applications

• Military systems requiring high-reliability voltage regulation
• Aerospace circuits where failure is not tolerated
• High-temperature electronic environments

Single Zener Diodes Procurement Notes

Verify the specific suffix 'DUS' against official Microchip documentation to confirm tape-and-reel packaging and exact tolerance specifications. Ensure compatibility with MIL-PRF-19500/533 standards if military qualification is required. Confirm RoHS status as non-compliant for sensitive applications.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface-mount Zener diode is needed for high-reliability applications. The 82 V rating suits specific reference voltage requirements. Consider the 220 Ohm dynamic impedance for noise-sensitive designs. Verify thermal management capabilities for the 500 mW dissipation limit in enclosed spaces.

Single Zener Diodes Part Context

This device belongs to the 1N63xx series of Zener voltage regulators. These components are designed as surface-mount equivalents for traditional axial leaded packages. The series provides industry-standard voltage options with robust construction suitable for critical infrastructure and defense electronics.

Single Zener Diodes Replacement Considerations

Compatible replacements include other JANTXV1N6346 variants such as JANTXV1N6346CUS or JANTXV1N6346CUS/TR, provided the package type and tolerance meet design requirements.
