Procurement Notes
This component has been officially transitioned to End of Life status by Central Semiconductor Corp. Availability is restricted to existing stock only, as no new production runs are scheduled. Buyers should verify current inventory levels with authorized distributors before finalizing orders, as replacement parts are not currently designated by the manufacturer.
Selection Notes
Engineers selecting this part must account for its discontinued status when designing new products. The SOT-363 package requires specific footprint considerations during PCB layout. Designers should evaluate alternative triple Zener diode packages if long-term supply stability is required for mass production environments.
Part Context
The CMKZ5258B BK belongs to the broader CMKZ5221B through CMKZ5261B series manufactured by Central Semiconductor Corp. This series encompasses various Zener voltage options ranging from 2.4V to 47V, all sharing the same triple isolated SOT-363 packaging architecture and electrical characteristics structure.
Replacement Considerations
No official replacement part numbers are listed by Central Semiconductor Corp. for this component. The manufacturer indicates that availability is limited to stock only without direct substitutes provided in their discontinuation notice.
