Overview
The CMKZ5224B TR is a surface mount triple isolated silicon Zener diode from the CMKZ5221B series, manufactured by Central Semiconductor Corp. It utilizes an ULTRAmini SOT-363 case and contains three independent Zener diodes with a 5% tolerance. The nominal Zener voltage is 2.8 V, ranging from 2.660 V to 2.940 V at a test current of 20 mA. Maximum dynamic impedance is 30 Ω at IZT and 1400 Ω at IZK. Reverse current is limited to 75 μA at VR = 1.0 V. Power dissipation is 200 mW, with an operating junction temperature range of -65 °C to +150 °C.

Procurement Notes
This component has been officially transitioned to End of Life (EOL) status by Central Semiconductor Corp. Replacement parts are not available; only existing stock may be sourced. Last purchase orders must be placed within six months of the notice date, with final shipments occurring twelve months after the notice. Minimum order quantities may apply during this period.
Selection Notes
Select this part when a compact triple isolated Zener solution is required for low-voltage regulation. Verify that the 2.8 V nominal voltage and 200 mW total power dissipation meet circuit requirements. Ensure compatibility with the SOT-363 footprint and confirm that the EOL status aligns with long-term production plans.
Part Context
The CMKZ5224B TR belongs to the CMKZ5221B through CMKZ5261B series of surface mount triple isolated silicon Zener diodes. These devices share the same ULTRAmini SOT-363 packaging and general electrical characteristics, differing primarily in Zener voltage ratings across the series range.
Replacement Considerations
No replacement part numbers are available for this discontinued series. Only existing stock can be procured. Contact [email protected] for assistance locating alternate sources if necessary.
