Overview
The CMKZ5236B 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 7.5 V (range 7.125 V to 7.875 V) at a test current of 20 mA. Each diode supports a maximum power dissipation of 200 mW and operates within a junction temperature range of -65 °C to +150 °C. The device features a maximum Zener impedance of 6.0 Ω at IZT and 500 Ω at IZK, with a reverse current of 3.0 μA at 6.0 V and a temperature coefficient of +0.058 %/°C.
Feature Summary
- Triple isolated configuration providing three independent Zener diodes in a single compact surface mount package
- Designed for industrial, commercial, entertainment, and computer applications requiring space-efficient voltage regulation
Applications
- Industrial control systems
- Commercial electronic equipment
- Computer circuitry
Procurement Notes
This component has been officially classified as End of Life by Central Semiconductor Corp. No new production orders are accepted. Availability is restricted to existing stock only. Verification of genuine inventory status through authorized distributors is required before procurement consideration.
Selection Notes
Select this part for designs requiring three isolated 7.5 V references in a small footprint. Verify that the 200 mW per-diode power rating and SOT-363 thermal characteristics meet the specific application requirements. Note that the device is discontinued and no direct manufacturer replacements are available.
Part Context
The CMKZ5236B belongs to the CMKZ5221B series, which covers Zener voltages from 2.4 V to 75 V. All devices in this series share the same ULTRAmini SOT-363 package and triple isolation architecture, differing primarily in their nominal voltage and associated electrical parameters such as impedance and temperature coefficients.
Replacement Considerations
No replacement part numbers are available from Central Semiconductor for this discontinued series. Designers must identify alternative components from other manufacturers that match the SOT-363 package, triple isolation topology, and 7.5 V Zener specifications.
