Procurement Notes

Verify the specific ordering suffix corresponds to the required tape and reel configuration, such as standard reel or cut tape options. Confirm that the application voltage does not exceed the 1.9V maximum rating. Ensure thermal design accounts for the small 1x1mm package footprint. Check RoHS compliance status if required by project specifications. Validate pinout compatibility during PCB layout phase.

Selection Notes

Select this component for applications requiring reverse blocking in sub-1.9V environments. It is suitable where space constraints necessitate a 1mm square package. Choose this part when low on-resistance is critical for efficiency at 1A loads. Consider alternatives if higher voltage inputs or bidirectional switching are needed. Evaluate thermal performance given the limited surface area.
