Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with design requirements. Confirm that the JANTX level meets the necessary quality assurance standards for the intended application. Cross-reference the manufacturing lot and compliance documentation to validate authenticity and traceability before integration into production.

Single Zener Diodes Selection Notes

Select this component when a 20 V Zener voltage with ±5% tolerance is required in an axial leaded package. Ensure the 1 W power dissipation rating aligns with the thermal management capabilities of the target circuit. Consider the extended temperature range and military qualification if the environment demands higher reliability than commercial grade parts provide.

Single Zener Diodes Part Context

This part belongs to the established 1N3016B-1 through 1N3045B-1 series of 1 Watt glass case Zener diodes. The JANTX designation indicates a specific military qualification level within the broader family of hermetically sealed devices available from Microchip Technology. These components are engineered for consistent performance in demanding operational conditions.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same manufacturer's lineup may include other variants from the 1N30xxB-1 series with different voltage ratings but identical packaging and qualification levels. Verify pinout and electrical characteristics match before substitution.
