Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm tape and reel specifications. Ensure that the component meets RoHS compliance requirements for the intended manufacturing process. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement orders.
Selection Notes
Select this component when a precise 2.2 V reference is required in a compact surface-mount footprint. Consider the negative temperature coefficient inherent to low-voltage Zener diodes during thermal design. Evaluate the 120 Ω dynamic resistance to ensure it aligns with the noise and impedance constraints of the target circuit application.
