CMKZ5236B TR

Overview

The CMKZ5236B 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 7.5 V and a tolerance of ±5%. Each diode operates at a test current of 20 mA, featuring a maximum dynamic impedance of 6.0 Ω and a reverse current of 3.0 μA. The device supports a power dissipation of 200 mW per diode 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 needing compact power management solutions
• Computer hardware utilizing space-constrained circuit designs

Procurement Notes

This component has been officially classified as End of Life (EOL) by the manufacturer. Replacement availability is restricted to existing stock only, with no new production scheduled. Buyers must verify current inventory levels through authorized distributors or direct supplier channels before committing to orders, as supply is finite and subject to depletion without restocking capabilities.

Selection Notes

Select this part when a design requires three isolated Zener references in a minimal footprint. Verify that the 7.5 V nominal voltage and 20 mA test current align with circuit requirements. Ensure thermal constraints accommodate the 200 mW dissipation rating per diode in the SOT-363 package. Confirm compatibility with surface mount assembly processes suitable for the specified case outline.

Part Context

The CMKZ5236B belongs to the CMKZ5221B series, which spans various Zener voltages from 2.4 V to 47 V. All devices in this series share the same triple-isolated SOT-363 packaging and electrical characteristics structure, differing primarily in breakdown voltage and associated temperature coefficients. This specific variant targets the 7.5 V segment of the product line.

Replacement Considerations

No official replacement part numbers are available from Central Semiconductor for this EOL component. Procurement is limited to remaining stock only. Designers should evaluate alternative triple-Zener packages from other manufacturers if long-term supply continuity is required.
