Procurement Notes
This component has been officially transitioned to End of Life status by Central Semiconductor Corp. No new production orders are accepted; availability is restricted to existing stock only. Verify part authenticity and storage conditions carefully when sourcing from secondary distributors due to the discontinued manufacturing status.
Selection Notes
Select this component for designs requiring three isolated Zener references in a minimal footprint. Ensure the circuit accommodates the specific 2.8 V nominal voltage and 20 mA test current requirements. Note that higher voltage options exist within the series but may require special ordering or alternative selection.
Part Context
The CMKZ5224B BK belongs to the CMKZ5221B through CMKZ5261B series of triple isolated silicon Zener diodes. All devices in this family share the same SOT-363 ULTRAmini package and 200 mW power dissipation rating, differing primarily in their specific Zener voltage ratings and corresponding marking codes.
Replacement Considerations
No direct replacement part numbers are listed by the manufacturer. Availability is limited to stock only. Contact [email protected] for assistance in locating alternate sources or suitable substitutes.
