Overview
The CMKZ5242B BK is a surface mount triple isolated silicon Zener diode from the Central Semiconductor CMKZ5221B series, housed in an ULTRAmini SOT-363 package. It contains three independent Zener diodes with a nominal voltage of 12 V (range 11.40 V to 12.60 V) tested at 20 mA. Each diode features a maximum dynamic impedance of 30 Ω and a reverse current of 1.0 μA at 9.1 V. The device supports a power dissipation of 200 mW and operates within a junction temperature range of -65 °C to +150 °C.
Feature Summary
- Triple isolated configuration integrating three independent Zener diodes into a single compact surface mount package
- Designed for industrial, commercial, entertainment, and computer applications requiring space-efficient voltage regulation
- Provides precise voltage control with 5% tolerance across the series
Applications
- Industrial equipment voltage regulation
- Commercial electronic circuit protection
- Entertainment system power management
- Computer application voltage reference
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific marking code '8SCT' matches the datasheet specifications. Check for End-of-Life status implications regarding availability and lead times before finalizing procurement decisions.
Selection Notes
Select this component when a triple isolated Zener array is required in an SOT-363 footprint. Ensure the design accommodates the 200 mW total power dissipation limit. Verify that the 12 V nominal voltage aligns with the target circuit requirements and that the operating temperature range meets environmental conditions.
Part Context
This part belongs to the CMKZ5221B through CMKZ5261B series of triple isolated silicon Zener diodes. The series offers various voltage options packaged in the ULTRAmini SOT-363 case. The CMKZ5242B specifically provides the 12 V nominal rating within this lineup.
Replacement Considerations
Official documentation lists no direct replacement part numbers for the CMKZ5242B BK. The product is classified as End of Life with stock only availability. Alternative sourcing requires consulting manufacturer engineering support for potential substitutes.
