CMPZDA13V TR PBFREE

Overview

The CMPZDA13V TR PBFREE is a dual Zener diode manufactured by Central Semiconductor Corp, housed in an SOT-23 surface-mount package. It features two independent Zener diodes connected in series within a single compact footprint. The device provides a nominal breakdown voltage of 13V per diode with a maximum power dissipation of 500mW. Key electrical parameters include a reverse leakage current of 1µA at the rated voltage and a forward voltage drop of 1.2V. It operates reliably across a temperature range from -65°C to +150°C junction temperature.

Feature Summary

• Dual configuration for space-constrained circuit designs
• High thermal stability suitable for demanding environments
• Compact SOT-23 surface-mount packaging

Applications

• Voltage reference circuits requiring dual rails
• Over-voltage protection stages
• Clamping applications in signal conditioning

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when placing orders. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure component authenticity by sourcing from authorized distributors only. Check for any recent Product Change Notifications (PCNs) that may affect pinout or material composition.

Selection Notes

Select this component when dual isolated Zener references are needed in minimal board space. Compare total power dissipation capabilities against thermal constraints of the PCB layout. Verify that the 13V breakdown voltage aligns precisely with circuit requirements. Consider the SOT-23 package dimensions for mechanical fitment during the design phase.
