JAN1N4129DUR-1/TR

Single Zener Diodes Overview

The JAN1N4129DUR-1/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation and protection applications. It features a nominal Zener voltage of 62 V with a maximum power dissipation of 500 mW. The device exhibits a reverse leakage current of 10 nA at 18 V and a forward voltage of 1.1 V at 200 mA. Its impedance (Zzt) is specified at 500 Ohms. The component operates within a temperature range of -65°C to 175°C and is housed in the DO-213AA surface-mount package.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with tight tolerance characteristics suitable for sensitive circuitry
• Engineered for high-temperature operation up to 175°C to withstand harsh environmental conditions
• Utilizes a compact surface-mount DO-213AA package for efficient board space utilization

Single Zener Diodes Applications

• Voltage regulation in military-grade power supply circuits
• Over-voltage protection for sensitive electronic components
• Reference voltage generation in aerospace instrumentation

Single Zener Diodes Procurement Notes

Verify that the ordering suffix /TR confirms tape-and-reel packaging configuration. Ensure the part number matches the specific JAN prefix for military qualification standards. Confirm RoHS compliance status as required by project specifications. Validate that the manufacturer is Microchip Technology to avoid counterfeit risks. Check for any recent Product Change Notifications affecting assembly sites or labeling.

Single Zener Diodes Selection Notes

Select this component when a 62 V Zener voltage is required in a surface-mount format. The DO-213AA package offers a small footprint compared to through-hole alternatives. Consider the 500 mW power rating for thermal management requirements. The wide operating temperature range supports deployment in extreme environments where standard commercial parts would fail.

Single Zener Diodes Part Context

This component belongs to the JAN series of Zener diodes produced by Microchip Technology. The JAN prefix indicates compliance with MIL-PRF-19500/437 military performance specifications. The DUR-1 suffix typically denotes a specific variant within the family, while /TR specifies the reel packaging method for automated assembly processes.

Single Zener Diodes Replacement Considerations

JAN1N4129DUR-1 is a parameter-equivalent alternative without the reel packaging. JANTX1N4129DUR-1 and JANTXV1N4129DUR-1 are also listed as parameter equivalents, offering potential substitution options depending on specific quality tier requirements.
