Procurement Notes
Verify the specific ordering suffix to confirm package quantity and reel specifications. Confirm that the HE3 designation aligns with required AEC-Q101 qualification levels. Ensure the SOT-23 footprint matches the target PCB layout dimensions. Validate RoHS compliance requirements against project specifications before finalizing procurement orders.
Selection Notes
Select this component when a dual serial Schottky diode topology is required within a minimal SOT-23 footprint. The low forward voltage drop makes it suitable for efficient signal rectification. Verify thermal resistance limits under expected ambient conditions. Consider the 30 V reverse voltage rating relative to peak circuit voltages to ensure adequate safety margins during operation.
