1N4113UR

Single Zener Diodes Overview

The 1N4113UR is a surface mount Zener diode manufactured by Microchip Technology. It utilizes the DO-213AA (SMB) package and provides a nominal voltage of 19 V with a power dissipation rating of 500 mW. The device features a standard tolerance of ±5% and operates within a junction temperature range of -65°C to +175°C. It serves as the surface mount equivalent to the JEDEC registered axial leaded 1N4113 series, offering round-end construction for automated assembly.

Single Zener Diodes Feature Summary

• Surface mount configuration compatible with automated pick-and-place equipment
• Internal metallurgical bond option available in specific suffix variants
• High thermal stability suitable for demanding industrial environments

Single Zener Diodes Applications

• Voltage regulation in compact electronic circuits
• Overvoltage protection for sensitive semiconductor components
• Reference voltage generation in precision measurement systems

Single Zener Diodes Procurement Notes

Verify the exact suffix designation when ordering, as variations such as -1 indicate internal metallurgical bonding which may affect qualification status. Confirm RoHS compliance requirements, as standard versions may not meet current environmental directives. Check for military-grade equivalents like JANTX or JAN if radiation hardness or specific reliability standards are required for the application.

Single Zener Diodes Selection Notes

Select this component when a robust surface mount solution is needed for 19 V regulation. Ensure the PCB footprint matches the DO-213AA dimensions. Consider the thermal derating curve if operating near the maximum junction temperature limit. Verify that the 500 mW power rating is sufficient for the expected load conditions without excessive heat buildup.

Single Zener Diodes Part Context

This part belongs to the broader family of glass passivated Zener diodes offered by Microchip. It corresponds to the axial 1N4113 but is optimized for surface mount technology. The series includes various voltage ratings from low values up to higher voltages, all sharing similar physical characteristics and mounting profiles for design flexibility.
