Single Zener Diodes Procurement Notes

Verify the manufacturer marking on the component body to confirm it originates from Microchip Technology or its predecessor entities such as Microsemi. Ensure the package type matches the required axial lead configuration for your assembly process. Cross-reference the part number with official distributor catalogs to validate authenticity and avoid counterfeit components during sourcing.

Single Zener Diodes Selection Notes

Select this component when a precise 140V reference is required with a 3W power handling capability. Consider the ±5% tolerance for applications allowing moderate voltage variation. Evaluate thermal management requirements to ensure the ambient temperature does not exceed the derating limits specified in the datasheet for continuous operation.

Single Zener Diodes Part Context

This component belongs to the standard Zener diode family used for discrete voltage control. It serves as a fundamental passive element in analog and mixed-signal designs. The part number follows the JEDEC numbering system common for silicon rectifier and regulator diodes, indicating its standardized electrical characteristics and mechanical form factor.

Single Zener Diodes Replacement Considerations

Substitute parts must match the 140V Zener voltage, 3W power rating, and ±5% tolerance. Verify that alternative manufacturers offer compatible axial packages and similar thermal resistance values to ensure equivalent performance in existing designs.
