Procurement Notes
This component is classified as End of Life (EOL). No new production orders are accepted. Availability is restricted to existing stock only. Verify EOL status and stock availability directly with the manufacturer or authorized distributors before design finalization.
Selection Notes
Select this part for designs requiring three isolated Zener references in a small footprint. Ensure the 200 mW per-diode power rating and 5% voltage tolerance meet circuit requirements. Note that higher voltage devices in this series may require special ordering.
Part Context
The CMKZ5231B belongs to the CMKZ5221B through CMKZ5261B series of triple isolated silicon Zener diodes. This series provides multiple voltage options within the same SOT-363 package, allowing designers to utilize consistent footprints across different voltage requirements.
Replacement Considerations
No direct replacement part numbers are available. The manufacturer lists 'N/A, Stock Only' for all variants in this series. Contact [email protected] for assistance locating alternate sources.
