Overview
The CMKZ5235B BK is a surface mount triple isolated silicon Zener diode from the CMKZ5221B series by Central Semiconductor Corp. It houses three independent Zener diodes in an ULTRAmini SOT-363 package with a 5% voltage tolerance. Each diode operates at a nominal Zener voltage of 6.8V, tested at a current of 20mA. The maximum reverse leakage current is 3.0µA at 5.0V, and the maximum temperature coefficient is +0.050%/°C. The device supports a power dissipation of 200mW 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 surface mount package
- Designed for industrial, commercial, entertainment, and computer applications requiring multiple voltage references
- Utilizes ULTRAmini SOT-363 case for space-constrained PCB layouts
Applications
- Industrial control systems
- Commercial equipment
- Entertainment electronics
- Computer hardware
Procurement Notes
This component has been officially transitioned to End of Life (EOL) status by Central Semiconductor Corp. according to Product Notice PDN01128. No new production orders are accepted; availability is restricted to existing stock only. Verify EOL status directly with authorized distributors before initiating procurement processes.
Selection Notes
Select this part when a design requires three isolated Zener references in a minimal footprint. Ensure the circuit accommodates the specific 6.8V nominal voltage and 20mA test current requirements. Consider thermal constraints as the total package dissipation is limited to 200mW per diode at 25°C ambient conditions.
Part Context
The CMKZ5235B BK belongs to the CMKZ5221B through CMKZ5261B series of triple isolated silicon Zener diodes. This series offers various voltage options within the same SOT-363 package format, allowing designers to standardize on a single package type while selecting different voltage ratings across the product line.
Replacement Considerations
No direct replacement part numbers are available from Central Semiconductor Corp. for this discontinued series. The manufacturer indicates that replacements are not applicable and availability is limited to stock only. Contact [email protected] for assistance locating alternate sources.
