Single Zener Diodes Procurement Notes

Verify the specific suffix and qualification level when ordering, as the base part number may correspond to commercial grades while military variants require distinct suffixes. Confirm package orientation and pinout compatibility during integration. Ensure storage conditions align with moisture sensitivity levels defined in the datasheet. Cross-reference manufacturer documentation for any recent design changes or obsolescence notices prior to final procurement decisions.

Single Zener Diodes Selection Notes

Select this component for designs requiring robust surface mount Zener regulation with wide thermal tolerance. The DO-213AA package offers compact footprint advantages over axial leads. Consider the 500 mW power rating for thermal management calculations. Verify that the 25V breakdown voltage matches circuit requirements without exceeding maximum ratings under transient conditions.

Single Zener Diodes Part Context

This device belongs to the 1N4099 through 1N4135 series of 0.5-watt glass surface mount Zener diodes manufactured by Microchip Technology. These components are engineered for general-purpose voltage regulation tasks where space constraints necessitate surface mount technology. The series provides standardized voltage options across a broad spectrum, ensuring availability for diverse electronic design needs.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N4117 variants such as JANTX1N4117UR-1 for qualified levels. Commercial equivalents must match the 25V Zener voltage, 500 mW power rating, and DO-213AA package dimensions. Verify electrical parameters like impedance and leakage current to ensure functional parity in critical applications.
