JANTXV1N6317

Single Zener Diodes Overview

The JANTXV1N6317 is a military-qualified Zener voltage regulator from the Microchip Technology series, designed for high-reliability applications. It features a nominal Zener voltage of 5.1 V with a tolerance of 5%. The device operates within a temperature range of -65°C to +175°C and has a maximum power dissipation of 500 mW. Key electrical parameters include a maximum reverse leakage current of 5 µA, a Zener impedance of 14 Ohms at a test current of 20 mA, and a forward voltage of 1.4 V at 1 A. The component is available in surface-mount B-SQ-MELF packages or through-hole DO-35 configurations.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless-glass construction using internal metallurgical bonds for enhanced durability.
• Qualified per MIL-PRF-19500/533 standards for critical environments where failure is not tolerated.
• Operates across an extended junction temperature range suitable for demanding conditions.

Single Zener Diodes Applications

• High-reliability aerospace systems
• Military-grade electronic circuits
• Critical voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify that the specific suffix (e.g., US for SMT, DUS for THT) matches the required package type. Confirm the QPL status if strict military qualification is mandated. Check for RoHS compliance requirements as indicated by the manufacturer's documentation. Ensure the ordering code aligns with the desired tolerance level and testing conditions specified in the datasheet.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V reference is needed in extreme thermal environments. Choose the SMT variant for compact board layouts or the axial leaded version for traditional mounting. Consider the 5% tolerance and 14 Ohm impedance for standard regulation needs. Evaluate the 500 mW power rating against circuit load requirements.

Single Zener Diodes Part Context

This part belongs to the 1N63xx series of 0.5 W glass Zener diodes. It shares the hermetic sealing technology with other variants in the family but differs in voltage ratings and package styles. The JANTXV designation indicates a specific quality level within the broader military-qualified product line offered by Microchip.

Single Zener Diodes Replacement Considerations

Substitutes must match the 5.1 V Zener voltage, 500 mW power rating, and MIL-PRF-19500/533 qualification. Verify package compatibility between SMT and THT options before swapping.
