1N4105DUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4105DUR-1/TR is a surface mount Zener diode with an 11V nominal voltage and 1% tolerance. It operates in the DO-213AA glass package, rated for 0.5W power dissipation at 25°C. The device features a metallurgical bond and hermetic sealing, qualified to JANS levels per MIL-PRF-19500/435. It supports operation from -65°C to +175°C junction temperature.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF package with internal metallurgical bond
• Qualified to JANS reliability levels for high-reliability applications
• Low noise density performance suitable for sensitive circuits
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad current and temperature ranges
• High-reliability aerospace and defense electronics
• Radiation-hardened circuit designs
• Precision reference voltage generation

Single Zener Diodes Procurement Notes

Verify that the ordering suffix TR indicates tape and reel packaging as specified in the mechanical section. Confirm the D suffix denotes 1% voltage tolerance. Ensure the JAN prefix or equivalent military qualification level matches the project requirements before procurement.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode with tight 1% voltage tolerance is required. It serves as the surface mount equivalent to the axial-leaded 1N4105 series. Consider its radiation hardness and low capacitance characteristics for specialized environments.

Single Zener Diodes Part Context

This part belongs to the 1N4099 through 1N4135 series of 500 mW Zener diodes. It is available in commercial CDLL versions and various military qualification levels including JAN, JANTX, and JANTXV. The series covers voltages from 1.8V to 100V with multiple tolerance options.

Single Zener Diodes Replacement Considerations

Direct equivalents include the CDLL4105-1 commercial version. Axial-leaded replacements are the 1N4105-1 series. Verify package compatibility and thermal derating curves when substituting.
