Overview
The CMPZDA20V TR TIN/LEAD is a dual Zener diode manufactured by Central Semiconductor Corp, housed in an SOT-323-3 surface-mount package. It features a nominal Zener voltage of 20 V with a power dissipation rating of 275 mW. The device exhibits a maximum reverse leakage current of 3 uA and a Zener impedance of 10 Ohms at a test current of 5 mA. Operating temperatures range from -65 C to +150 C. The component utilizes a tin/lead lead finish and is supplied in reel packaging for automated assembly processes.
Feature Summary
- Dual configuration integrating two Zener diodes within a compact three-terminal SOT-323 package
- Designed for low-leakage voltage reference applications requiring stable regulation
- Capable of operation across extended industrial temperature ranges
Applications
- Voltage reference circuits in precision measurement equipment
- Clamping and protection stages in signal conditioning paths
- Biasing networks in analog integrated circuit interfaces
Procurement Notes
Verify the specific electrical parameters against the official Central Semiconductor datasheet prior to integration. Confirm that the tin/lead termination finish aligns with project material compliance requirements. Ensure the SOT-323-3 footprint matches the intended PCB layout design specifications exactly.
Selection Notes
Select this component when a dual Zener topology is required in a minimal surface-mount form factor. Evaluate the 275 mW power dissipation limit against expected thermal conditions. Compare the 10 Ohm impedance specification against circuit sensitivity requirements for noise and regulation performance.
Part Context
This part belongs to the CMPZDA series of dual Zener diodes produced by Central Semiconductor. The series provides matched or independent dual configurations in small outline packages. These components serve as alternatives to discrete single-diode solutions where space conservation is critical.
Replacement Considerations
Consult manufacturer cross-reference lists for electrically equivalent dual Zener devices in SOT-323 packages. Verify pinout compatibility and voltage tolerance specifications before substituting with alternative suppliers.
