Single Zener Diodes 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.

Single Zener Diodes 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.

Single Zener Diodes 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.

Single Zener Diodes 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.
