The Central Semiconductor CMSZDA33V TR PBFREE is a dual, common anode silicon zener diode in the SOT-323 surface-mount package. It provides a nominal zener voltage of 33 V with a test current of 2.0 mA and a maximum dynamic impedance of 80 Ω at Izt. The device dissipates up to 275 mW per diode and operates within a junction temperature range of -65 °C to +150 °C. Maximum reverse leakage current is specified at 0.05 µA at 32 V, while the maximum zener current reaches 23.1 mA.
Verify the specific ordering suffix against manufacturer documentation to confirm lead-free status or special plating requirements. Confirm that the requested quantity aligns with standard reel packaging specifications provided by the supplier. Ensure compatibility with automated pick-and-place equipment due to the small outline package dimensions.
Select this component when a dual zener arrangement with a common anode is required in a compact SOT-323 footprint. Evaluate the 275 mW power dissipation limit relative to the expected thermal environment. Consider the 80 Ω dynamic impedance specification for applications requiring moderate voltage stability under varying current conditions.
This part belongs to the CMSZDA series, which covers nominal voltages from 2.4 V to 47 V. All devices in this family share identical physical dimensions and pin configurations, differing only in their electrical characteristics such as zener voltage, impedance, and temperature coefficients. The series is designed for general-purpose surface-mount voltage regulation tasks.
Direct replacements must match the SOT-323 package, dual common anode topology, and 33 V nominal voltage. Verify that substitute components meet or exceed the 275 mW power dissipation rating and operate within the -65 °C to +150 °C temperature range.
