JANTX1N4128UR-1/TR

Single Zener Diodes Overview

The JANTX1N4128UR-1/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA (SMB) package. It features a nominal Zener voltage of 60 V with a tolerance of ±5% and a maximum power dissipation of 500 mW. The device exhibits a maximum impedance of 400 Ohms and a forward voltage of 1.1 V at 200 mA. It operates within a temperature range of -65°C to 175°C junction temperature and complies with MIL-PRF-19500/435 standards for military-grade reliability.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with tight tolerance specifications suitable for sensitive circuit protection.
• Engineered for high-temperature operation up to 175°C junction temperature for harsh environments.
• Utilizes a compact surface-mount DO-213AA package for automated assembly integration.

Single Zener Diodes Applications

• Military aerospace voltage reference circuits
• Harsh environment overvoltage protection
• High-reliability power supply regulation

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel configuration for automated placement. Confirm compliance with specific military qualification requirements such as MIL-PRF-19500/435. Ensure the DO-213AA footprint aligns with the design layout. Validate thermal management capabilities for the specified junction temperature range during system integration.

Single Zener Diodes Selection Notes

Select this component when a 60 V Zener voltage with ±5% tolerance is required in a surface-mount format. Consider the 500 mW power rating against expected load conditions. Evaluate the 400 Ohm impedance for noise sensitivity. Compare against standard commercial variants if military qualification is not mandatory for the application.

Single Zener Diodes Part Context

This part belongs to the JANTX series of Zener diodes from Microchip Technology, which are qualified for military and aerospace applications. The 'UR' designation indicates a round-end voltage regulator style in a surface-mount package. It serves as a ruggedized alternative to commercial equivalents, ensuring performance under extreme thermal and mechanical stress conditions defined by defense standards.

Single Zener Diodes Replacement Considerations

JANTX1N4128C-1/TR offers equivalent electrical parameters in a through-hole DO-204AH package. JANTX1N4128D-1 provides similar characteristics but may differ in packaging or specific military lot traceability requirements. Verify pinout compatibility and thermal resistance differences when substituting surface-mount parts with axial lead equivalents.
