Overview
The CMKZ5222B BK is a surface mount triple isolated silicon Zener diode from the Central Semiconductor CMKZ5221B series, housed in an ULTRAmini SOT-363 package. It contains three independent Zener diodes with a nominal voltage of 2.5V (range 2.375V to 2.625V) and a 5% tolerance. Each diode operates at a test current of 20mA, featuring a maximum dynamic impedance of 30Ω and reverse current of 0.25mA. The device supports a power dissipation of 200mW and functions within a temperature range of -65°C to +150°C.
Feature Summary
- Triple isolated configuration providing three independent Zener diodes in a single compact surface mount package
- Designed for industrial, commercial, entertainment, and computer applications requiring space-efficient voltage regulation
Applications
- Industrial control systems
- Commercial electronic equipment
- Entertainment system circuitry
- Computer hardware components
Procurement Notes
This component has been officially classified as End of Life by Central Semiconductor Corp. No new production orders are accepted; availability is restricted to existing stock only. Buyers must verify supplier inventory status carefully before committing to purchases, as supply is finite and subject to depletion without replenishment.
Selection Notes
Designers should evaluate alternative components due to the discontinued status of this part number. Verify that replacement devices match the required SOT-363 footprint, triple isolation architecture, and specific electrical parameters such as the 2.5V nominal Zener voltage and 5% tolerance to ensure circuit compatibility.
Part Context
The CMKZ5222B BK belongs to the CMKZ5221B through CMKZ5261B series of surface mount triple isolated silicon Zener diodes. This series utilizes the ULTRAmini SOT-363 case to provide multiple voltage regulation channels in a minimal board area, targeting applications where space constraints are critical.
Replacement Considerations
No direct replacement part numbers are provided by the manufacturer. The official notice indicates 'N/A, Stock Only' for all series variants, meaning no equivalent active product is currently recommended or available from Central Semiconductor.
