Overview
The CMKZ5231B BK is a surface mount triple isolated silicon Zener diode from Central Semiconductor Corp, housed in an ULTRAmini SOT-363 package. It contains three independent Zener diodes with a nominal voltage of 5.1V (range: 4.845V to 5.335V) at a test current of 20mA. Each diode has a maximum power dissipation of 200mW and operates within a junction temperature range of -65°C to +150°C. The device features a maximum reverse current of 5.0µA and a temperature coefficient of ±0.030%/°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 equipment voltage regulation
- Commercial electronics circuit protection
- Entertainment system power management
- Computer application voltage reference
Procurement Notes
This component is classified as End of Life (EOL). Availability is restricted to existing stock only; no new production orders are accepted. Verify current inventory status with authorized distributors before design finalization. Last purchase order deadlines may apply based on manufacturer notices. Confirm RoHS compliance and lead-free plating specifications during procurement verification.
Selection Notes
Select this component when a triple isolated Zener array is required in an SOT-363 footprint. Ensure the 5.1V nominal voltage and 20mA test current align with circuit requirements. Consider the 200mW per-diode power dissipation limit and thermal resistance of 625°C/W for heat management. Verify that the ±5% tolerance meets precision needs for the specific application environment.
Part Context
The CMKZ5231B belongs to the CMKZ5221B through CMKZ5261B series of surface mount triple isolated silicon Zener diodes. This series utilizes the ULTRAmini SOT-363 case for high-density PCB mounting. All devices in this series share identical physical dimensions and pin configurations while varying in Zener voltage characteristics across the series range.
Replacement Considerations
No direct replacement part numbers are available from Central Semiconductor for this EOL component. Stock-only availability is confirmed. Contact [email protected] for assistance locating alternate sources or technical data for potential substitutes.
