JANTX1N755DUR-1

Single Zener Diodes Overview

The JANTX1N755DUR-1 is a silicon unidirectional Zener diode manufactured by Microchip Technology. It provides a nominal Zener voltage of 7.5 V with a maximum power dissipation of 500 mW. The component utilizes a DO-213AA (MELF) surface-mount package and meets the MIL-PRF-19500/127 specification for the JANTX quality level. It operates within an extended temperature range from -65°C to +175°C, featuring a low reverse leakage current of 2 µA at 5 V and a Zener impedance of 4 Ohms.

Single Zener Diodes Feature Summary

• Qualified per MIL-PRF-19500/127 for the JANTX military grade level
• Utilizes a hermetically sealed glass MELF (DO-213AA) surface-mount package
• Supports operation in extreme environments ranging from -65°C to +175°C

Single Zener Diodes Applications

• Military aerospace electronic systems requiring high-reliability voltage regulation
• Harsh environment circuit protection and reference voltage generation
• Avionics equipment operating under extreme thermal conditions

Single Zener Diodes Procurement Notes

Verify that the specific suffix UR-1 corresponds to the intended reel packaging configuration as defined by the manufacturer's official documentation. Confirm compliance with the JANTX quality level requirements specified in MIL-PRF-19500/127 before procurement. Ensure the ordering documentation explicitly references the correct part number to avoid confusion with commercial or JAN variants.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface-mount Zener diode is required for high-reliability applications. The JANTX designation ensures screening beyond standard commercial levels. Consider the MELF package geometry for automated assembly processes where space constraints preclude through-hole mounting. Verify that the 500 mW power rating aligns with the thermal management capabilities of the target circuit design.

Single Zener Diodes Part Context

This device belongs to the 1N755 series of silicon Zener diodes produced by Microchip Technology. The series encompasses various qualification levels including JAN, JANTX, and JANTXV, all adhering to the MIL-PRF-19500/127 standard. The JANTX1N755DUR-1 specifically denotes the enhanced reliability tier packaged in a leadless glass MELF format suitable for surface-mount technology integration.

Single Zener Diodes Replacement Considerations

Direct replacements include the JANTX1N755D-1 for through-hole DO-35 implementations and the JANTX1N755CUR-1/TR for commercial-grade MELF equivalents. Cross-reference electrical parameters such as Zener voltage tolerance and impedance to ensure functional compatibility within the existing circuit design.
