Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure correct packaging and testing levels. Confirm that the DO-35 package dimensions align with the target PCB footprint. Validate that the component meets all required radiation hardness or qualification standards for the intended deployment environment before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed Zener diode is required for extreme thermal conditions. The DO-35 through-hole format suits legacy or high-vibration assemblies. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specific 2.7 V regulation point under expected load currents.

Single Zener Diodes Part Context

This part belongs to the JANTX series of single Zener diodes, representing a higher reliability tier within Microchip's diode portfolio. The 'TX' designation indicates enhanced screening compared to standard commercial variants. It serves as a ruggedized alternative for applications where standard semiconductor packages fail to meet durability requirements.

Single Zener Diodes Replacement Considerations

Direct substitutes include JANTXV1N4618-1 for voltage regulator variants and JANTX1N4618CUR-1/TR for surface mount equivalents. Verify pinout compatibility and thermal resistance characteristics when transitioning between package types.
