- Commercial electronic equipment
- Computer circuitry
Procurement Notes
This component has been officially classified as End of Life (EOL) by Central Semiconductor Corp. The manufacturer indicates that no direct replacement part numbers are available for this specific model. Procurement is restricted to existing stock only, and new production orders cannot be placed. Verification of current stock availability through authorized distributors is required before integration into designs.
Selection Notes
Designers should verify the thermal resistance and power dissipation limits carefully when using multiple diodes simultaneously within the SOT-363 package. Since the series is discontinued, alternative components must be sourced from other manufacturers. Ensure that any substitute part matches the 6.2 V nominal voltage, 5% tolerance, and physical footprint requirements for the application.
Part Context
The CMKZ5234B belongs to the CMKZ5221B through CMKZ5261B series of triple isolated silicon Zener diodes. This series was designed to offer high reliability in a small form factor. The entire series has transitioned to End of Life status, meaning manufacturing has ceased across all voltage variants within this product line.
Replacement Considerations
No official replacement part numbers are listed by Central Semiconductor for the CMKZ5234B TR. The datasheet explicitly states 'N/A, Stock Only' for this item. Engineers must identify third-party equivalents independently.
