JANTX1N976C-1/TR

Single Zener Diodes Overview

The JANTX1N976C-1/TR is a hermetically sealed silicon Zener diode manufactured by Microchip Technology. It provides a nominal Zener voltage of 43 V with a tight tolerance of ±2%. The device operates in the Through-Hole DO-204AH (DO-35) axial package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 500 nA at 33 V, a Zener impedance of 93 Ohms, and a forward voltage of 1.1 V at 200 mA. It is qualified under MIL-PRF-19500/117 for military applications and functions reliably within an extended temperature range from -65°C to +175°C.

Single Zener Diodes Procurement Notes

Verify that the specific suffix matches the required packaging configuration, as standard bulk variants may differ from reel configurations. Confirm that the component meets all necessary environmental certifications for your specific deployment. Ensure compatibility with existing assembly processes for axial leaded components. Cross-reference the manufacturer's latest documentation to confirm current production status and any potential obsolescence notices before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a stable 43 V reference is required in space-constrained axial packages. The low leakage current makes it suitable for high-impedance sensing applications. Consider the thermal derating curves if operating near the upper temperature limit. Verify that the 500 mW power rating aligns with the expected dissipation in the target circuit design to ensure long-term reliability.

Single Zener Diodes Part Context

This part belongs to the 1N976 series of Zener diodes, widely used in military and industrial electronics. The 'JANTX' prefix indicates a specific quality level within the Microchip portfolio, denoting enhanced screening and reliability testing compared to commercial grades. It serves as a critical passive component in analog signal conditioning and power management architectures.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N976C-1 and JAN1N976C-1/TR. Other manufacturers offer equivalent 43 V Zener diodes in DO-35 packages, but verify hermetic sealing requirements and MIL-PRF-19500/117 compliance for direct replacement in qualified designs.
