1N4102UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4102UR/TR is a glass surface mount Zener voltage regulator with a nominal breakdown voltage of 8.7V at a test current of 250µA. It operates within a temperature range of -65°C to +175°C and dissipates up to 0.5W. The device features a hermetically sealed DO-213AA (SOD80/MLL34) MELF package, offering minimal capacitance and inherent radiation hardness.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF package
• Inherently radiation hard design
• ESD non-sensitive per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation in harsh environments
• Radiation-hardened circuit designs
• Surface mount power supply applications

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application. The 'TR' suffix indicates tape and reel packaging. Confirm RoHS compliance status if required by your manufacturing process. Ensure the ordering part number matches the exact voltage tolerance needed, as standard tolerances are +/-5% without additional suffixes.

Single Zener Diodes Selection Notes

Select this component for applications requiring high reliability and radiation resistance. The DO-213AA package provides a surface mount equivalent to axial-leaded JEDEC registered parts. Consider the thermal resistance characteristics when designing the PCB footprint to ensure proper heat dissipation during operation.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR through 1N4135UR series of 0.5-watt glass surface mount Zeners. These devices provide a broad selection of voltages from 1.8 to 100 volts. They serve as direct surface mount replacements for traditional axial-leaded components while maintaining similar electrical performance profiles.

Single Zener Diodes Replacement Considerations

Direct surface mount equivalents include the MLL4102 variant. For military specifications, consider the 1N4102UR-1 series which offers internal metallurgical bonding options.
