1N4696UR-1

Overview

The Microchip Technology 1N4696UR-1 is a Zener voltage regulator diode designed for surface mount applications. It features a DO-213AA (MELF) package and provides a nominal Zener voltage of 9.1 V with a standard tolerance of 5%. The device supports a maximum power dissipation of 500 mW and operates within an extended temperature range from -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 1 µA, a test current of 50 µA, and a forward voltage of 1.1 V at a forward current of 200 mA.

Feature Summary

• Features internal metallurgical bond construction for enhanced reliability in harsh environments
• Provides stable voltage regulation across a broad operating current and temperature range
• Utilizes hermetically sealed glass MELF packaging for environmental protection

Applications

• Voltage reference circuits requiring high stability
• Overvoltage protection in sensitive electronic systems
• Clamping applications in aerospace and defense equipment

Procurement Notes

Verify the specific suffix configuration when ordering, as it dictates the package type and screening level. Confirm that the required voltage tolerance and power dissipation ratings align with the circuit design specifications. Ensure compatibility with surface mount assembly processes suitable for the DO-213AA outline. Check for any specific military or industrial screening requirements if applicable to the end-use environment.

Selection Notes

Select this component for designs necessitating a reliable surface mount Zener diode with a 9.1 V regulation point. The DO-213AA package offers a compact footprint suitable for space-constrained PCB layouts. Consider the 500 mW power rating and wide temperature capability when evaluating thermal management needs. This part is appropriate for applications where long-term stability and resistance to environmental stressors are critical performance factors.

Part Context

This component belongs to the 1N4678 through 1N4717 series of 0.5 W Zener voltage regulators manufactured by Microchip Technology. The series encompasses various voltage options ranging from 1.8 V to 43 V. The 1N4696UR-1 variant specifically denotes the surface mount version with internal metallurgical bonding, distinguishing it from axial-leaded equivalents like the 1N4696-1.

Replacement Considerations

Equivalent parts include the 1N4696-1TR for axial-leaded configurations or other manufacturers' DO-213AA Zener diodes with matching 9.1 V and 500 mW ratings. Verify pinout compatibility and thermal characteristics before substitution.
