1N4108UR

Single Zener Diodes Overview

The Microchip Technology 1N4108UR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 14 V with a tolerance of 5%. The device operates in the SMD/SMT form factor within a DO-213AA-2 package, also known as MELF. It has a maximum power dissipation of 500 mW and a Zener impedance of 200 Ohms. The component supports an operating temperature range from -65 °C to +175 °C. Maximum reverse leakage current is specified at 50 nA, with a test current of 250 uA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a round-end voltage regulator design suitable for surface mount assembly.
• Engineered for high-temperature reliability with an extended operational range up to 175 °C.
• Features low reverse leakage current characteristics to minimize power loss in off-state conditions.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise regulation in compact layouts
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix UR against official Microchip documentation to confirm the exact package type and manufacturing lot details. Ensure compatibility with surface mount assembly processes given the DO-213AA-2 form factor. Confirm RoHS status and military qualification requirements if applicable to the target system. Cross-reference datasheet revisions to ensure parameter consistency.

Single Zener Diodes Selection Notes

Select this component when a 14 V regulation point is required in a surface mount configuration. The DO-213AA-2 package offers space efficiency compared to through-hole alternatives. Consider the 200 Ohm impedance value for dynamic load regulation needs. Verify thermal management capabilities align with the 500 mW dissipation limit in the final enclosure environment.

Single Zener Diodes Part Context

This part belongs to the 1N4108 series of Zener diodes manufactured by Microchip Technology. It serves as the surface mount equivalent to axial leaded variants like the 1N4108D-1. The series is commonly used in general-purpose voltage regulation tasks where size constraints favor MELF packages over traditional glass axial designs.
