Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required voltage tolerance and package type. Confirm the product status as a production data sheet item. Ensure the application does not require automotive qualification, as this specific series is not qualified for automotive use according to the provided documentation.

Single Zener Diodes Selection Notes

Select this component for designs requiring a compact surface-mount voltage regulator with a nominal breakdown voltage of 56 V. The SOT323 package is suitable for space-constrained PCB layouts. Consider the ±5% tolerance specification when designing circuits where precise voltage referencing is critical.

Single Zener Diodes Part Context

This component is part of the Nexperia BZX84W series, which comprises 74 types covering nominal working voltages from 2.4 V to 75 V. The series utilizes the SC-70 plastic surface-mounted package with three leads. The BZX84W-B56F specifically denotes the variant with ±5% voltage tolerance.

Single Zener Diodes Replacement Considerations

Other BZX84W series variants with different nominal voltages or tolerance codes may serve as functional substitutes if the voltage rating aligns with design requirements. Verify pinout compatibility and thermal characteristics before substitution.
