Procurement Notes
This component has been officially transitioned to End of Life status by Central Semiconductor Corp. Current availability is restricted to existing stock only, with no new production scheduled. Buyers must verify stock existence directly with suppliers, as standard ordering channels do not support active procurement for this discontinued part number.
Selection Notes
Designers should evaluate alternative components due to the End of Life status of the CMKZ5238B BK. Verify that replacement parts match the required SOT-363 footprint and electrical specifications, specifically the 8.7 V nominal Zener voltage and isolation requirements. Confirm thermal resistance and power dissipation limits align with the target application's operating conditions.
Part Context
The CMKZ5238B BK belongs to the CMKZ5221B through CMKZ5261B series of surface mount triple isolated silicon Zener diodes manufactured by Central Semiconductor Corp. This series utilizes the ULTRAmini SOT-363 package to house three distinct Zener diodes, offering a space-efficient solution for multi-voltage reference or protection needs in compact electronic designs.
Replacement Considerations
No direct replacement part numbers are listed in the official discontinuation notice (PDN01128). The document indicates 'N/A, Stock Only' for all variants in the series, including the CMKZ5238B BK.
