Diode Arrays Procurement Notes

Verify the specific ordering suffix 'H' indicates reel packaging when sourcing. Confirm AEC-Q101 compliance requirements match your design specifications. Check for alternative packages if board space constraints differ from SOT-416-3 dimensions. Ensure thermal management aligns with the 150 mW dissipation limit in your final assembly.

Diode Arrays Selection Notes

Select this component for designs requiring dual diodes in a minimal footprint with automotive certification. Compare against single-diode alternatives if only one channel is needed to optimize cost. Consider the 20 V reverse voltage limit for circuit protection roles. Evaluate the 150°C junction temperature capability for high-thermal environments.
