Overview
The CMKZ5239B TR is a surface mount triple isolated silicon Zener diode from Central Semiconductor Corp, packaged in an ULTRAmini SOT-363 case. It contains three independent Zener diodes with a nominal voltage of 9.1 V and a tolerance of ±5%. Each diode operates at a test current of 20 mA, featuring a maximum dynamic impedance of 10 Ω and a knee impedance of 600 Ω. The device supports a power dissipation of 200 mW per diode and functions within a junction temperature range of -65°C to +150°C.
Feature Summary
- Triple isolated configuration providing three independent Zener diodes in a single compact package
- Designed for industrial, commercial, entertainment, and computer applications
- Surface mount construction utilizing the ULTRAmini SOT-363 case form factor
Applications
- Industrial control systems requiring multiple voltage references
- Commercial equipment needing compact regulation solutions
- Computer hardware utilizing space-constrained layouts
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 series. Procurement should focus on verifying existing stock availability or consulting engineering support for alternative sourcing strategies, as standard production has ceased.
Selection Notes
Designers must account for the specific pinout of the SOT-363 package when integrating this triple-diode array. Verify that the required circuit topology utilizes all three isolated channels effectively to justify the package selection over discrete components. Ensure thermal management aligns with the 200 mW dissipation rating per diode under operating conditions.
Part Context
The CMKZ5239B belongs to the CMKZ5221B through CMKZ5261B series, which covers a wide range of Zener voltages from approximately 2.4 V to 47 V. All devices in this series share the same physical packaging and isolation architecture but differ in their electrical characteristics, specifically voltage, impedance, and temperature coefficients.
Replacement Considerations
No official replacement part numbers are listed by the manufacturer. The datasheet explicitly states 'N/A, Stock Only' for this item. Engineers should contact Central Semiconductor engineering support directly for assistance in locating alternate sources or suitable cross-references.
