Procurement Notes
Verify component status before procurement as the CMKZ5228B BK is classified as End of Life (EOL). Availability is restricted to existing stock only, with no new production scheduled. Confirm final shipment dates and minimum order quantities directly with authorized distributors or Central Semiconductor representatives prior to placing orders.
Selection Notes
Select this component when a triple isolated Zener array is required in a small surface mount footprint. Ensure the design accommodates the specific 3.9 V nominal voltage and 23 Ω impedance limits. Verify that the SOT-363 thermal resistance and power dissipation ratings meet the system's thermal management requirements under expected operating conditions.
Part Context
This part belongs to the CMKZ5221B through CMKZ5261B series, which provides various Zener voltage options within the same ULTRAmini SOT-363 package. All devices in this series share identical physical dimensions and pin configurations, differing primarily in their electrical characteristics such as breakdown voltage and temperature coefficients.
Replacement Considerations
No direct replacement part numbers are available for the CMKZ5228B BK. The manufacturer indicates that availability is limited to stock only. Engineers must identify alternative suppliers or redesign circuits using other available triple isolated Zener arrays if this component is no longer obtainable.
