Overview
The CMKZ5233B TR is a surface mount triple isolated silicon Zener diode from Central Semiconductor Corp, housed in an ULTRAmini SOT-363 package. It integrates three independent Zener diodes within a single component, each featuring a nominal voltage of 6.0 V with a 5% tolerance range spanning 5.700 V to 6.300 V. The device operates at a test current of 20 mA, exhibiting a maximum dynamic impedance of 7.0 Ω and a knee impedance of 1600 Ω. Each diode dissipates up to 200 mW total power, supports junction temperatures from -65°C to +150°C, and maintains a reverse leakage current of 5.0 μA at 3.5 V.
Feature Summary
- Triple isolated configuration integrating three independent Zener diodes in one compact package
- ULTRAmini SOT-363 surface mount case designed for space-constrained industrial and commercial applications
- 5% voltage tolerance ensuring precise regulation across the specified temperature range
Applications
- Industrial control systems requiring multiple voltage references
- Commercial equipment needing compact multi-channel protection
- Entertainment electronics utilizing limited board space
- Computer applications requiring isolated signal conditioning
Procurement Notes
Verify End-of-Life status before procurement as the series has been transitioned to discontinued status by the manufacturer. Confirm availability through stock-only channels or authorized distributors, as new production may be unavailable. Request official documentation to validate current supply chain constraints and ensure compliance with project timelines.
Selection Notes
Select this component when designing circuits requiring three isolated Zener references in a minimal footprint. Ensure the design accommodates the 200 mW total power dissipation limit and the specific 6.0 V nominal voltage. Verify that the SOT-363 package dimensions align with the PCB layout requirements and thermal management strategy.
Part Context
This part belongs to the CMKZ5221B through CMKZ5261B series of triple isolated silicon Zener diodes. The series provides various voltage options within the same SOT-363 package form factor, allowing designers to standardize on a single package type while selecting different voltage ratings based on circuit requirements.
Replacement Considerations
No direct replacement part numbers are listed in the official discontinuation notice. Availability is restricted to existing stock only. Designers should evaluate alternative triple-diode packages or discrete components if stock is exhausted.
