Single Zener Diodes Procurement Notes

Verify that the specific suffix CUR-1 corresponds to the required tape-and-reel or bulk packaging format as defined by the manufacturer's official documentation. Confirm compliance requirements, noting that RoHS status may be non-compliant for this specific military-grade part number. Ensure the procurement channel provides valid traceability documentation consistent with Microchip's quality standards for JANTXV series components.

Single Zener Diodes Selection Notes

Select this component when a precise 33 V reference is required in a compact surface-mount form factor. The DO-213AA-2 package offers a small footprint compared to through-hole alternatives like DO-35. Consider the 58 Ohm impedance characteristic for circuit stability. Verify thermal management capabilities align with the 0.5 W power rating under expected operating conditions.

Single Zener Diodes Part Context

This part belongs to the JANTXV1N97x series of Zener diodes produced by Microchip Technology (formerly Microsemi). These components are engineered for high-reliability applications, often serving in military and aerospace sectors where robust performance under extreme conditions is mandatory. The series shares common packaging and construction methodologies while varying in voltage specifications.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTXV1N973 variants such as JANTXV1N973D-1 for through-hole mounting or JANTXV1N973C-1 if leaded versions are acceptable. Cross-brand replacements require careful verification of Zener voltage tolerance, power dissipation ratings, and package dimensions to ensure functional compatibility.
