Single Zener Diodes Procurement Notes

Verify the ordering suffix "-TP" indicates tape-and-reel packaging containing 3000 pieces per reel. Confirm RoHS compliance status through official MCC documentation or authorized distributors. Ensure sourcing from authorized channels to guarantee genuine parts with full traceability and adherence to handling standards.

Single Zener Diodes Selection Notes

Select this component for designs requiring a 16 V regulation point in space-constrained PCB layouts. The SOT-323 package offers significant size reduction compared to axial leads. Consider the 200 mW power limit and thermal resistance when determining heat dissipation requirements in the final assembly environment.

Single Zener Diodes Part Context

This part belongs to the MMBZ5221BW through MMBZ5259BW series, covering a wide voltage range from 2.4 V to 39 V. All devices in this family share the same SOT-323 plastic package and 200 mW power dissipation rating, differing primarily in their specific Zener voltage breakdown characteristics and corresponding marking codes.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SOT-323 Zener diodes rated at 16 V with similar impedance and power specifications. Verify that any substitute matches the 200 mW dissipation limit and operating temperature range of -55°C to +150°C to ensure functional equivalence in existing circuit designs.

Single Zener Diodes FAQ

What is the maximum reverse leakage current for the MMBZ5246BW-TP?

The maximum reverse leakage current is 0.1 µA when measured at a reverse voltage of 12 V.

How is the Zener impedance defined for this component?

The Zener impedance is derived from the AC voltage resulting when an AC current with an RMS value equal to 10% of the DC Zener current is superimposed on the DC bias.
