Overview
The CMPZDA22V TR TIN/LEAD is a dual silicon Zener diode manufactured by Central Semiconductor, housed in an SOT-323 surface-mount package. It features a common cathode configuration with a nominal Zener voltage of 22 V and a maximum power dissipation of 275 mW per diode at 25°C ambient temperature. The device exhibits a maximum dynamic impedance of 100 Ω and operates within a junction temperature range of -65°C to +150°C. Testing is conducted at a current of 5 mA, ensuring stable voltage regulation for precision circuit applications.
Feature Summary
- Dual Zener diodes integrated into a single compact surface-mount package
- Common cathode configuration simplifies circuit layout and component count
- High thermal stability supporting operation up to 150°C junction temperature
Applications
- Voltage reference circuits requiring dual regulated rails
- Overvoltage protection stages in industrial control systems
- Signal conditioning modules in commercial entertainment equipment
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure that the requested quantity aligns with standard reel sizes to avoid partial reel handling issues during assembly processes.
Selection Notes
Select this component when space-constrained designs require two independent Zener references in a minimal footprint. Confirm that the 22 V breakdown voltage matches the target regulation requirement and that the 275 mW power rating accommodates the expected operating current without exceeding thermal limits.
Part Context
This part belongs to the CMPZDA series of dual silicon Zener diodes from Central Semiconductor. The series offers various voltage options in the SOT-323 package, providing designers with flexible solutions for dual-channel voltage regulation needs in portable and dense electronic assemblies.
Replacement Considerations
Consult official substitution guides for equivalent dual Zener devices in SOT-323 packages. Verify pin compatibility and electrical parameters such as Zener voltage tolerance and dynamic impedance before implementing any alternative components.
