1N4116UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4116UR/TR is a glass surface mount Zener voltage regulator with a nominal breakdown voltage of 24V. It operates within the 1N4099UR through 1N4135UR series and utilizes a DO-213AA (SOD80/MLL34) MELF package. The device provides a steady-state power dissipation of 0.5 watts at an end-cap temperature below 100°C or ambient temperature below 25°C. Electrical characteristics include a maximum dynamic impedance of 150 ohms, a test current of 250 µA, and a maximum reverse leakage current of 40 µA. The component supports tape and reel packaging per EIA-481-1-A standards.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF package
• Internal metallurgical bond option available via suffix
• Minimal capacitance for high-frequency stability
• Radiation hard construction

Single Zener Diodes Applications

• Voltage regulation in harsh environments
• Surface mount circuit design
• Military qualification applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements. The TR suffix indicates tape and reel packaging configuration. Ensure the selected variant matches the required tolerance and termination finish specifications for the target application environment.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required. The 1N4116UR offers a 24V reference point with standard tolerances. Consider the -1 suffix if internal metallurgical bonding is necessary for enhanced reliability in extreme conditions.

Single Zener Diodes Part Context

This part belongs to the Microsemi Scottsdale Division 1N4099UR through 1N4135UR series. These devices are designed as surface mount equivalents to JEDEC registered axial-leaded Zeners. The series covers a broad voltage range from 1.8V to 100V in a compact glass package suitable for automated assembly processes.

Single Zener Diodes Replacement Considerations

Equivalent axial-leaded parts include the 1N4116. Surface mount alternatives within the same family include MLL4116. Verify pinout compatibility and thermal derating curves when substituting.
