Single Zener Diodes Procurement Notes

Verify the manufacturer origin carefully, as this part number history involves multiple entities including Microsemi and Microchip Technology. Confirm that the specific unit received matches the required metallurgical bond specification associated with the UR-1 suffix. Ensure compatibility with the intended surface-mount assembly process for the DO-213AA package before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode with enhanced structural integrity via metallurgical bonding is required. It serves as the SMT equivalent to axial-leaded versions in the same series. Consider the DO-213AA footprint constraints and ensure the voltage rating fits the specific circuit design needs within the broader 1N47xx series options.

Single Zener Diodes Part Context

This device belongs to the extensive family of 0.5-watt Zener diodes produced by Microchip Technology. The series spans from 1.8 volts to 43 volts, offering standard 5% tolerances. The UR-1 designation specifically denotes the surface-mount variant with the internal metallurgical bond, distinguishing it from standard glass axial-leaded or non-bonded surface-mount counterparts in the product portfolio.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N4717 variants such as the axial-leaded 1N4717 or 1N4717A, provided the package form factor change is acceptable. Surface-mount equivalents like the 1N4717UR without the metallurgical bond may function electrically but differ in construction. Verify exact voltage tolerance and power dissipation ratings when cross-referencing.
