1N4116UR-1/TR

Single Zener Diodes Overview

The 1N4116UR-1/TR is a single surface-mount Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 24 V with a maximum dynamic impedance of 150 Ω and a power dissipation rating of 500 mW. The device operates within a temperature range of -65 °C to +175 °C and utilizes the DO-213AA (SMB) package. It is supplied in tape and reel packaging for automated assembly processes.

Single Zener Diodes Feature Summary

• Designed for surface-mount technology applications using the DO-213AA package
• Provides stable voltage regulation with a nominal reference voltage of 24 V
• Capable of operating at high temperatures up to 175 °C

Single Zener Diodes Applications

• Voltage regulation circuits
• Over-voltage protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape and reel packaging rather than bulk. Confirm RoHS compliance status as some variants may be non-compliant. Ensure the DO-213AA footprint matches the design layout. Check lead times as they may vary significantly from standard estimates.

Single Zener Diodes Selection Notes

Select this component when a 24 V Zener voltage is required in a compact surface-mount form factor. The 500 mW power rating suits moderate current applications. Consider the 150 Ω dynamic impedance for regulation precision requirements. Verify thermal management capabilities for operation near the upper temperature limit.

Single Zener Diodes Part Context

This part belongs to Microchip's single Zener diode family, often marketed under the round-end voltage regulator designation. It shares the DO-213AA package with other variants in the series, such as the 1N4111UR-1 and 1N4106UR-1, which offer different voltage ratings but similar physical dimensions and mounting styles.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 24 V Zener voltage, 500 mW power dissipation, and DO-213AA package constraints.
