CMPZDA2V4 TR PBFREE

Overview

The CMPZDA2V4 TR PBFREE is a dual silicon Zener diode manufactured by Central Semiconductor Corp, housed in an SOT-23 surface-mount package. It features a common cathode configuration with a nominal Zener voltage of 2.4 V and a maximum power dissipation of 350 mW per diode at 25°C ambient temperature. The device supports an operating and storage temperature range from -65°C to +175°C, with a thermal resistance (junction-to-ambient) of 429°C/W. Key electrical characteristics include a maximum forward voltage of 0.9 V at 10 mA forward current and a maximum dynamic impedance of 100 Ω.

Feature Summary

• Dual Zener diodes integrated in a single compact SOT-23 surface-mount package
• Common cathode configuration for simplified circuit design
• Extended high-temperature operation capability up to 175°C
• Low forward voltage drop characteristic for efficient signal handling

Applications

• Industrial control systems requiring precise voltage regulation
• Commercial equipment utilizing low-power reference circuits
• Entertainment electronics needing stable DC voltage levels
• Computer applications involving signal clamping or protection

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the part number matches the exact series designation to avoid confusion with similar variants in the CMPZDC family. Cross-reference datasheet revisions to confirm updated electrical limits.

Selection Notes

Select this component for designs requiring dual Zener functions within limited board space. The common cathode arrangement simplifies layout compared to discrete components. Verify that the 350 mW power rating suffices for the intended thermal environment. Consider the 100 Ω dynamic impedance for noise-sensitive applications where lower impedance might be required.

Part Context

This component belongs to the CMPZDA series of surface-mount dual Zener diodes from Central Semiconductor. It shares the physical SOT-23 footprint with other devices in the lineup but differs in internal Zener voltage ratings. The series is designed to replace multiple discrete diodes, reducing assembly complexity and improving reliability in dense PCB layouts.

Replacement Considerations

Direct substitutes may include other dual Zener diodes in SOT-23 packages with matching 2.4 V voltage and 350 mW power ratings. Verify pinout compatibility and thermal resistance values before substitution. Check if alternative manufacturers offer equivalent common cathode configurations with similar dynamic impedance specifications.
