Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1 against the manufacturer's latest datasheet to confirm pinout orientation and marking codes. Ensure the procurement channel provides traceability documentation required for quality assurance. Confirm that the delivered components match the specified DO-213AA-2 package dimensions and lead finish requirements before integration into production lines.

Single Zener Diodes Selection Notes

Select this component when a 30 V regulation point is required in a surface-mount design. Consider the 500 mW power dissipation limit and thermal management needs during PCB layout. Evaluate the 200 Ohm impedance value for noise sensitivity in the target application. Compare the -65°C to +175°C temperature range against environmental constraints to ensure long-term stability under extreme conditions.

Single Zener Diodes Part Context

This part belongs to the 1N4120 series of Zener diodes manufactured by Microchip Technology. The series offers various voltage ratings within a standardized surface-mount form factor. The UR-1 designation typically indicates a specific tape-and-reel or bulk packaging configuration distinct from through-hole variants. This family is commonly used in industrial and commercial electronics requiring reliable voltage clamping.

Single Zener Diodes Replacement Considerations

Direct substitutes include JANTX1N4120UR-1 and JAN1N4120UR-1, which share identical electrical specifications and package dimensions. Verify compatibility with radiation-hardened or military-grade variants if the application demands enhanced reliability standards beyond standard commercial specifications.
