Designed for industrial, commercial, entertainment, and computer applications
Features 5% voltage tolerance for precise regulation requirements

Applications

Industrial control systems
Commercial electronic equipment
Entertainment system circuitry
Computer hardware protection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific marking code '1G8T' matches the physical device. Check for End of Life status as the series may be discontinued. Request updated datasheets to ensure electrical parameters align with design specifications before finalizing orders.

Selection Notes

Select this component when space-constrained designs require multiple isolated voltage references. Ensure the operating environment stays within the specified thermal limits. Verify that the 200mW power dissipation rating accommodates the expected load conditions. Consider the SOT-363 footprint compatibility during PCB layout planning.

Part Context

This part belongs to the CMKZ5221B through CMKZ5261B series, which offers various zener voltages in the same ULTRAmini SOT-363 package. The series provides consistent mechanical dimensions while varying electrical characteristics to suit different voltage reference needs across multiple industries.

Replacement Considerations

The CMKZ5255B series is classified as End of Life (EOL). No direct replacement part numbers are provided by the manufacturer. Stock availability may be limited to existing inventory only. Alternative sources must be evaluated carefully for parameter matching.
