1N4696UR-1/TR

Overview

The Microchip Technology 1N4696UR-1/TR is a surface mount Zener diode with a nominal voltage of 9.1 V and a standard tolerance of ±5%. It operates within a junction temperature range of -65 °C to +175 °C and dissipates up to 0.5 W. The device features a test current of 50 µA, a maximum reverse leakage current of 1.0 µA at 1.0 V, and a maximum DC Zener current of 52.4 mA. Packaged in a hermetically sealed DO-213AA MELF style, it includes an internal metallurgical bond for high reliability.

Feature Summary

• Internal metallurgical bond between metal slugs and silicon die for enhanced structural integrity.
• Hermetically sealed glass DO-213AA (MELF) surface mount package construction.
• Low capacitance characteristics suitable for sensitive circuit applications.
• Inherent radiation hardness compliant with MIL-STD-750 method 1020.

Applications

• Voltage regulation across broad operating current and temperature ranges.
• High-reliability aerospace and defense electronic systems.
• Radiation-hardened circuit protection designs.

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance levels and screening options. Ensure compatibility with RoHS requirements if applicable, as compliance varies by grade. Confirm that the tape and reel packaging aligns with automated assembly specifications before finalizing procurement orders.

Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability environments. The 1N4696UR-1 offers a 9.1 V regulation point with a low 50 µA test current. Consider the internal metallurgical bond for superior mechanical stability compared to standard commercial packages.

Part Context

This part belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5 W glass surface mount Zener voltage regulators. The series provides voltage selections from 1.8 V to 43 V. The UR-1 designation indicates a surface mount package with an internal metallurgical bond, serving as the equivalent to the JEDEC registered axial-leaded 1N4678 through 1N4717 series.

Replacement Considerations

Equivalent axial-leaded versions include the 1N4696-1 or 1N4696-1E3. Surface mount equivalents without the metallurgical bond are available in the standard 1N4696UR series. Verify pinout and thermal resistance differences when substituting.
