1N4118UR

Single Zener Diodes Overview

The 1N4118UR is a Zener voltage regulator diode manufactured by Microchip Technology. It features a nominal Zener voltage of 27 V with a 5% tolerance and a maximum power dissipation of 400 mW. The device utilizes a DO-213AA surface-mount package and operates within a temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 27 V with standard 5% tolerance
• Features internal metallurgical bonding for enhanced reliability
• Designed for surface-mount assembly in compact circuits

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for military qualification levels such as JAN or JANTX, as these affect compliance and availability. Confirm RoHS status if environmental regulations apply, noting that standard versions may not be compliant. Ensure the DO-213AA footprint matches the design layout before ordering.

Single Zener Diodes Selection Notes

Select this component when a 27 V Zener voltage is required in a surface-mount configuration. Consider the 400 mW power rating and operating temperature range to ensure suitability for the thermal environment. Verify if the internal metallurgical bond is necessary for the specific application's reliability standards.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR-1 through 1N4135UR-1 series of glass surface mount Zener diodes. These devices are surface-mount equivalents to JEDEC registered axial-leaded parts, offering similar electrical characteristics in a compact DO-213AA package suitable for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 27 V Zener diodes in the DO-213AA package from compatible manufacturers. For axial-leaded equivalents, consider the 1N4118 series. Verify pinout compatibility and power ratings when cross-referencing.
