Overview
The CMKZ5233B BK is a surface mount triple isolated silicon Zener diode from Central Semiconductor Corp, housed in an ULTRAmini SOT-363 package. It contains three independent Zener diodes with a nominal voltage of 6.0 V and a tolerance of ±5%. Each diode operates at a test current of 20 mA, featuring a maximum dynamic impedance of 7.0 Ω and a reverse current of 5.0 μA. The device supports a power dissipation of 200 mW and functions within a junction temperature range of -65°C to +150°C.
Feature Summary
- Triple isolated silicon Zener diodes integrated into a single compact surface mount package
- Designed for industrial, commercial, entertainment, and computer applications
- Provides independent voltage regulation for multiple circuits within limited board space
Applications
- Industrial control systems requiring multi-channel voltage reference
- Commercial equipment utilizing compact power management solutions
- Computer hardware needing isolated voltage regulation
- Entertainment electronics with space-constrained circuit designs
Procurement Notes
This component has been officially transitioned to End of Life status by the manufacturer. Current availability is restricted to existing stock only, as no new production runs are scheduled. Buyers should verify inventory levels carefully before placing orders, as supply is finite and subject to depletion without replenishment from the factory.
Selection Notes
Engineers selecting this part must account for its discontinued status when designing long-term products. The SOT-363 package provides three isolated channels, making it suitable for applications requiring multiple voltage references in a small footprint. Designers should evaluate the specific electrical characteristics against system requirements before committing to remaining stock.
Part Context
The CMKZ5233B belongs to the CMKZ5221B through CMKZ5261B series of triple isolated silicon Zener diodes. This series utilizes the ULTRAmini SOT-363 case to house three independent devices. The CMKZ5233B specifically offers a 6.0 V nominal Zener voltage, distinguishing it from lower or higher voltage variants within the same family.
Replacement Considerations
No direct replacement part numbers are available from Central Semiconductor Corp for this component. The manufacturer indicates that replacements are not applicable, and procurement is limited to stock only. Alternative sourcing strategies must be pursued if new production is required.
