1N4115UR

Single Zener Diodes Overview

The Microchip Technology 1N4115UR is a surface-mount Zener diode designed for voltage regulation applications. It features a 22V nominal Zener voltage and operates within the DO-213AA (SMB) package. The device exhibits a dynamic impedance of 150 Ohms, characteristic of its round-end voltage regulator design. This component provides stable reference voltages in compact electronic circuits requiring reliable surface-mount integration.

Single Zener Diodes Feature Summary

• Surface-mount construction utilizing the DO-213AA package format
• Round-end voltage regulator architecture for stable regulation
• Internal metallurgical bond structure for enhanced reliability

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection systems
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variations such as TR or -1 may indicate different packaging or screening levels. Confirm RoHS compliance status directly with the manufacturer, as documentation indicates non-compliance for certain variants. Ensure the selected part matches the required MIL-PRF-19500 qualification level if high-reliability standards are necessary for the application.

Single Zener Diodes Selection Notes

Select this component for designs requiring a 22V Zener reference in a surface-mount footprint. Consider the 150 Ohm dynamic impedance when designing for low-noise requirements. Verify that the thermal management capabilities of the DO-213AA package align with the power dissipation needs of the target circuit environment.

Single Zener Diodes Part Context

This part belongs to the family of 500 mW glass surface mount Zener diodes manufactured by Microchip. These devices serve as surface-mount equivalents to traditional axial-leaded JEDEC registered series. The internal metallurgical bonding technique distinguishes these components, offering improved mechanical stability and thermal performance compared to standard epoxy-sealed packages.

Single Zener Diodes Replacement Considerations

Equivalent parts include JANTXV1N4115UR-1 for screened military-grade versions. Commercial alternatives may exist within the same 22V Zener category, but pinout and package dimensions must be verified.
