JAN1N4135UR-1/TR

Single Zener Diodes Overview

The JAN1N4135UR-1/TR is a surface-mount Zener diode manufactured by Microchip Technology. It features a nominal voltage of 100 V with a tolerance of ±5% and a power dissipation rating of 500 mW. The device exhibits a maximum dynamic impedance of 1600 Ohms at the specified test current. It is housed in a DO-213AA (SOD-80) package, measuring approximately 3.7 mm in length and 1.7 mm in diameter. The component supports an operating temperature range from -65°C to +175°C and complies with MIL-PRF-19500/435 specifications for military-grade reliability.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 100 V with tight tolerance for precision circuit applications
• Operates reliably across extreme temperatures ranging from -65°C to +175°C
• Utilizes a compact surface-mount DO-213AA package for automated assembly integration

Single Zener Diodes Applications

• Military aerospace electronic systems requiring high-reliability voltage reference
• Aviation instrumentation circuits demanding wide thermal stability
• Defense communication equipment utilizing surface-mount voltage regulation

Single Zener Diodes Procurement Notes

Verify that the specific suffix UR-1/TR corresponds to the required tape-and-reel packaging configuration for your manufacturing line. Confirm compliance with MIL-PRF-19500/435 standards if military qualification is mandatory. Ensure the DO-213AA footprint matches your PCB design constraints. Check for any recent product change notices regarding assembly sites or material composition updates before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 100 V Zener reference is needed in a small surface-mount form factor. The 500 mW power rating suits low-current regulation tasks. Consider the 1600 Ohm dynamic impedance for noise-sensitive designs where higher impedance may impact regulation accuracy. Verify that the extended temperature range meets the environmental requirements of the target application environment.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes produced by Microchip Technology, formerly Microsemi. These components are designed for rugged environments and adhere to strict military performance standards. The JAN1N4135 variant specifically offers 100 V regulation in a round-end SMD package, distinguishing it from axial-lead counterparts like the JAN1N4135-1.

Single Zener Diodes Replacement Considerations

JAN1N4135UR-1 serves as a bulk-pack equivalent. JAN1N4135-1 is the axial leaded version. 1N4135UR-1/TR is the commercial grade alternative without military certification.
