Single Zener Diodes Procurement Notes

Verify the specific ordering suffix Q-13-F confirms the automotive grade designation and 10,000-unit tape and reel packaging configuration. Ensure compatibility with standard SOT23 footprint requirements during procurement planning. Confirm that the component meets all relevant environmental compliance standards required for the intended deployment environment.

Single Zener Diodes Selection Notes

Select this component when an automotive-rated Zener diode with a 4.3 V nominal breakdown voltage is required. The Q-13-F suffix indicates suitability for high-reliability environments compared to standard commercial grades. Consider the SOT23 package dimensions and thermal characteristics for integration into compact printed circuit board layouts.

Single Zener Diodes Part Context

This part belongs to the BZX84C series of 350mW surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.4 V to 51 V. The BZX84C4V3Q-13-F specifically represents the 4.3 V variant within this family, distinguished by its automotive qualification and specific packaging format.

Single Zener Diodes Replacement Considerations

Standard commercial equivalents such as BZX84C4V3-13-F may be considered if automotive qualification is not strictly required. Verify that any substitute maintains the same SOT23 package and electrical parameters.
