• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' against official Microchip documentation to confirm tolerance specifications, as generic listings may omit critical precision details. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity and traceability for this military-grade variant. Confirm RoHS compliance status if required by project specifications.

Single Zener Diodes Selection Notes

Select the JANTX1N4480C when a precise 43 V regulation point is required within a through-hole design constraint. The 1.5 W power rating allows for moderate current handling without excessive heat sinking. Consider the 40 Ohm impedance for noise sensitivity requirements. Verify that the DO-41 package dimensions fit the target PCB layout and that the thermal management strategy accommodates the expected power dissipation under worst-case conditions.

Single Zener Diodes Part Context

This component belongs to the JANTX series of Zener diodes produced by Microchip Technology, formerly Microsemi. The JANTX designation typically indicates a higher reliability grade compared to standard commercial parts, often intended for aerospace or defense applications. It shares the electrical characteristics of the commercial 1N4480C but adheres to stricter manufacturing controls and testing protocols defined by the manufacturer's quality standards.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent replacements include the commercial 1N4480C for non-critical applications. For radiation-hardened requirements, consider the JANS1N4480C. Verify pinout compatibility and thermal performance before substituting.
