Overview
The CMKZ5230B 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 4.7 V and a tolerance of ±5%. Each diode operates at a test current of 20 mA, featuring a maximum dynamic impedance of 19 Ω and a reverse current of 5.0 μA. The device supports a power dissipation of 200 mW and functions within a 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 in small form factors
Procurement Notes
This component has been officially classified as End of Life (EOL) by the manufacturer. Replacement options are not available through standard production channels. Procurement should focus on verifying stock availability from authorized distributors or legacy inventory sources, as new manufacturing orders cannot be placed.
Selection Notes
Engineers selecting this part must account for its EOL status when designing new products. Verify that the SOT-363 footprint matches existing PCB layouts. Consider alternative components with similar electrical characteristics if long-term supply stability is required for future production runs.
Part Context
The CMKZ5230B belongs to the CMKZ5221B series, which includes various Zener voltage options ranging from 2.4 V to 47 V. All devices in this series share the same triple-isolated SOT-363 packaging and general electrical structure, differing primarily in their specific Zener voltage ratings and associated marking codes.
Replacement Considerations
No direct replacement part numbers are provided by the manufacturer. The official notice indicates 'N/A, Stock Only' for all variants in this series, meaning no functional equivalent is currently recommended for new designs.
