1N4113UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4113UR/TR is a 0.5-watt glass surface mount Zener voltage regulator in the DO-213AA package. It provides a nominal Zener voltage of 19 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C and features a hermetically sealed construction. Electrical characteristics include a test current (IZT) of 250 µA, maximum Zener impedance (ZZT) of 0.05 Ω, and maximum reverse current (IR) of 40 µA at VR.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA surface mount package
• Inherently radiation hard design
• ESD nonsensitive per MIL-STD-750 Method 1020
• Minimal capacitance for high-frequency applications

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Reference voltage sources in radiation-hardened environments
• Protection circuits requiring ESD resistance

Single Zener Diodes Procurement Notes

Verify that the part number suffix 'TR' corresponds to the tape and reel packaging option as specified in the datasheet. Confirm the absence of additional suffixes such as '-1', 'C', or 'D' if standard 5% tolerance and non-military qualification are required. Ensure compatibility with RoHS compliant specifications indicated by the 'e3' designation in the series documentation.

Single Zener Diodes Selection Notes

Select this component when a 19 V Zener reference is needed in a compact surface mount form factor. The DO-213AA package serves as a surface mount equivalent to the axial-leaded DO-35/DO-7 packages. Consider the wide operating temperature range and radiation hardness for demanding environmental conditions compared to standard commercial alternatives.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR through 1N4135UR series of 0.5-watt glass surface mount Zener diodes manufactured by Microchip Technology (formerly Microsemi). These components are designed to replace traditional axial-leaded JEDEC registered Zener diodes while offering improved mechanical stability and suitability for automated surface mount assembly processes.

Single Zener Diodes Replacement Considerations

Direct surface mount equivalents include the MLL4113UR. For axial leaded replacements, the 1N4113 is the corresponding JEDEC registered part number.
