Procurement Notes
Verify the exact part number suffix against official manufacturer documentation before procurement. Confirm that the ordering suffix corresponds strictly to the plating finish or packaging format as defined in the datasheet. Ensure compatibility with RoHS directives if required by the target application specifications.
Selection Notes
Select this component when a dual Zener configuration with a common anode is required in a compact SOT-23 footprint. Evaluate the specific Zener voltage tolerance and impedance requirements against the circuit's load conditions. Consider the 350 mW power dissipation limit and thermal resistance when designing the PCB layout for adequate heat management.
