Overview
The CMKZ5239B BK is a triple isolated silicon Zener diode from the CMKZ5221B series by Central Semiconductor Corp. It features three independent Zener diodes in an ULTRAmini SOT-363 surface mount package with 5% voltage tolerance. The nominal Zener voltage is 9.1 V, ranging from 8.645 V to 9.555 V at a test current of 20 mA. Maximum reverse current is 3.0 µA at 7.0 V, and maximum Zener impedance is 600 Ω. Each diode dissipates up to 200 mW, operating within a junction temperature range of -65°C to +150°C.
Feature Summary

Procurement Notes
This component has been transitioned to End of Life status as per Central Semiconductor's Product Management Process. No new production orders are accepted. Availability is restricted to existing stock only. Customers must verify current inventory levels with authorized distributors before initiating any procurement activities.
Selection Notes
Select this device when space-constrained designs require multiple isolated voltage references. Verify that the 9.1 V nominal voltage and 600 Ω impedance meet circuit requirements. Ensure the SOT-363 footprint aligns with PCB layout constraints. Confirm thermal dissipation limits fit the specific application environment.
Part Context
The CMKZ5239B belongs to the CMKZ5221B through CMKZ5261B series, which offers various Zener voltages from 2.4 V to 47 V. All devices in this series share the same triple isolated SOT-363 packaging and 5% tolerance specifications, allowing for consistent design practices across different voltage requirements.
Replacement Considerations
No direct replacement part numbers are available from Central Semiconductor. The manufacturer indicates 'N/A, Stock Only' for all discontinued items in this series. Alternative sourcing requires identifying third-party equivalents or redesigning with currently manufactured components.
