Overview
The CMKZ5237B BK is a surface mount triple isolated silicon Zener diode from the CMKZ5221B series by Central Semiconductor Corp. It houses three independent Zener diodes in an ULTRAmini SOT-363 package with 5% voltage tolerance. Each diode operates at a nominal Zener voltage of 8.2V, tested at 20mA, with a maximum impedance of 8.0Ω and reverse current of 3.0μA. The device supports a power dissipation of 200mW per diode and functions within a junction temperature range of -65°C to +150°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 multiple voltage references
- ULTRAmini SOT-363 case format optimized for space-constrained printed circuit board layouts
Applications
- Industrial control systems requiring multiple regulated voltage rails
- Commercial equipment utilizing compact multi-channel voltage reference circuits
- Entertainment electronics integrating isolated signal conditioning paths
- Computer hardware employing dense surface mount voltage regulation modules
Procurement Notes
This component has been officially transitioned to End of Life status by Central Semiconductor Corp. Current availability is restricted to existing stock only, with no new production scheduled. Buyers should verify inventory levels carefully before ordering, as supply is finite and subject to depletion without replenishment from the manufacturer.
Selection Notes
Select this part when a design requires three isolated Zener diodes within a minimal footprint. Verify that the 8.2V nominal voltage and 200mW power rating align with circuit requirements. Note that the device is discontinued; ensure alternative sourcing strategies are established if long-term supply continuity is necessary for the product lifecycle.
Part Context
The CMKZ5237B BK belongs to the CMKZ5221B through CMKZ5261B series, which features triple isolated silicon Zener diodes in SOT-363 packages. This series provides various voltage options ranging from 2.4V to 47V, all maintaining 5% tolerance and identical thermal and mechanical characteristics across the lineup.
Replacement Considerations
No direct replacement part numbers are listed by the manufacturer. Availability is limited to stock only. Contact [email protected] for assistance locating alternate sources or suitable substitutes.
