Single Zener Diodes Procurement Notes

Verify the specific suffix US against the official datasheet to confirm the surface mount package type. Ensure the JAN prefix aligns with required military qualification standards. Confirm RoHS status as these devices may not be compliant. Validate the manufacturer source directly from Microchip documentation.

Single Zener Diodes Selection Notes

Select this component when hermetic sealing and extended temperature performance are mandatory. The SQ package requires compatible surface mount footprint design. Verify that the 68V regulation point matches circuit requirements. Consider thermal management for the specified power dissipation limits in enclosed spaces.

Single Zener Diodes Part Context

This part belongs to the 1N4485 series of Zener diodes, which includes various tolerance and package options. The JANTX designation indicates enhanced testing beyond standard JAN levels. The US suffix specifies the surface mount configuration, distinguishing it from through-hole variants like the DO-35 package.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTX1N4485US parts from authorized manufacturers. Cross-reference with JAN1N4485US if package compatibility allows. Verify electrical parameters match exactly before substitution.
