Single Zener Diodes Procurement Notes

Verify that the specific suffix CUS corresponds to the exact MIL-PRF-19500/406 qualification and ±2% tolerance required for your design. Confirm the package type is D-5A/SQ-MELF and check for RoHS compliance status as indicated in official datasheets. Ensure the supplier provides traceability documentation consistent with military-grade procurement requirements.

Single Zener Diodes Selection Notes

Select this component when a high-precision 18 V reference is needed in a surface-mount form factor. The ±2% tolerance offers better accuracy than standard commercial equivalents. Consider the 1.5 W power rating and 175°C operating limit for thermal management in enclosed or high-temperature designs compared to lower-rated alternatives.

Single Zener Diodes Part Context

This part belongs to the JANTXV series of Zener diodes from Microchip Technology, which are engineered for high-reliability applications.
