Overview
The CMSZDA12V TR PBFREE is a surface-mount dual common anode silicon zener diode from Central Semiconductor. It provides a nominal voltage of 12 V with a tolerance range of 11.4 V to 12.7 V at a test current of 5.0 mA. The device dissipates up to 275 mW and operates within a junction temperature range of -65 °C to +150 °C. Electrical characteristics include a maximum zener impedance of 25 Ω at the test current, a reverse leakage current of 0.1 µA at 9.1 V, and a thermal coefficient of 0.07 %/°C. It utilizes a SOT-323 package.

Procurement Notes
Verify the specific ordering suffix when purchasing. The PBFREE designation indicates lead-free plating, while other suffixes may denote different plating options or packaging variations. Confirm the exact part number matches the required electrical specifications and package type before finalizing procurement orders.
Selection Notes
Select this component based on the required 12 V nominal zener voltage and the 275 mW power dissipation limit. Ensure the circuit design accommodates the specified operating temperature range and that the SOT-323 package dimensions fit the intended layout constraints.
Part Context
This component belongs to the CMSZDA series, which covers nominal voltages from 2.4 V to 47 V. All devices in this series share the same dual common anode architecture and SOT-323 surface-mount package, allowing for consistent design practices across various voltage requirements.
Replacement Considerations
Direct replacements must match the dual common anode configuration, SOT-323 package, and 12 V nominal voltage. Verify that substitute components meet the 275 mW power dissipation and -65 °C to +150 °C operating temperature requirements.
