Procurement Notes

Verify the specific suffix designation during procurement to confirm qualification status. The -AQ suffix indicates AEC-Q101 qualified components, while other suffixes may denote different compliance levels. Ensure that the ordered part matches the required automotive or commercial grade specifications for your design. Confirm RoHS compliance and REACH registration details directly with the manufacturer before finalizing orders.

Selection Notes

Select this component for designs requiring compact surface-mount solutions with high-speed performance. The SOT-323 package offers space efficiency for dense PCB layouts. Consider the thermal resistance and power dissipation limits when designing for high ambient temperatures. Verify that the 85 V reverse voltage rating meets the circuit requirements. The low capacitance makes it suitable for high-frequency signal paths where parasitic effects must be minimized.
