1N4131UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4131UR/TR is a glass surface mount Zener voltage regulator with a nominal breakdown voltage of 75 V. It operates within a temperature range of -65°C to +175°C and dissipates up to 0.5 watts at an end cap temperature below 100°C. The device features a DO-213AA (MELF) package, a maximum reverse current of 40 µA, and a zener impedance of 0.01 Ω. It provides standard ±5% voltage tolerance and is supplied in tape and reel packaging.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF package construction
• Capable of regulating voltage across a broad operating current and temperature range
• Inherently radiation hard design
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation circuits requiring surface mount technology
• Radiation-hardened electronic systems
• High-temperature industrial applications

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application. The 'TR' suffix indicates tape and reel packaging. Confirm that the standard 5% tolerance meets your circuit specifications. Ensure the thermal management plan accounts for the 0.5-watt power dissipation limit relative to the FR4 PCB footprint.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability environments. The 1N4131UR offers a 75 V regulation point with low noise density. Consider the DO-213AA package dimensions for board layout compatibility. Verify that the operating temperature range aligns with your system's environmental constraints.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR through 1N4135UR series of 0.5-watt glass surface mount Zener regulators. These devices serve as surface mount equivalents to JEDEC registered axial-leaded parts. The series covers a wide voltage selection from 1.8 to 100 volts in standard tolerances.

Single Zener Diodes Replacement Considerations

JEDEC registered axial-leaded equivalents are available in the 1N4099 through 1N4135 series. Surface mount alternatives exist in the MLL4099 through MLL4135 numbering scheme. Military qualified versions with internal metallurgical bonds are identified by the '-1' suffix.
