Overview
The CMKZ5258B TR is a surface mount triple isolated silicon Zener diode from the Central Semiconductor CMKZ5221B series, packaged in an ULTRAmini SOT-363 case. It contains three independent Zener diodes with a nominal voltage of 36V (min 34.20V, max 37.80V) at a test current of 3.4mA. 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 Zener impedance of 70Ω at IZT and 700Ω at IZK, with a reverse current of 0.1μA at 27V. The thermal resistance is 625°C/W, and it carries a temperature coefficient of +0.093%/°C.
Feature Summary
- Triple isolated silicon Zener diodes integrated into a single ULTRAmini SOT-363 surface mount package
- Designed for industrial, commercial, entertainment, and computer applications
- Provides five percent tolerance on Zener voltage specifications
Applications
- Industrial equipment voltage regulation
- Commercial electronic circuit protection
- Entertainment system power management
- Computer application voltage reference
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific marking code 1J8T matches the datasheet requirements. Check for RoHS compliance status if required by assembly standards. Ensure storage conditions remain within specified limits to maintain reliability before soldering.
Selection Notes
Select this component when space-constrained designs require multiple isolated voltage references in a small footprint. Verify that the 36V nominal voltage aligns with circuit requirements. Consider the 200mW per-diode power dissipation limit during thermal analysis. Ensure the SOT-363 package dimensions fit the PCB layout constraints.
Part Context
This part belongs to the CMKZ5221B through CMKZ5261B series, which offers various Zener voltages from 2.4V to 47V in the same triple-isolated SOT-363 package. The series provides consistent mechanical and electrical characteristics across different voltage options, simplifying inventory management for multi-voltage designs.
