Procurement Notes
Verify the specific ordering code suffix to confirm compliance requirements. The HE3 designation indicates AEC-Q101 qualification for automotive standards, whereas the E3 variant denotes commercial grade RoHS compliance. Ensure the selected part matches the required environmental and reliability specifications for the intended application before procurement.
Selection Notes
Select this component when a dual Schottky diode with a common cathode topology is required in a compact SOT-23 footprint. The HE3 suffix provides necessary automotive qualification (AEC-Q101) compared to standard commercial grades. Consider the 30 V reverse voltage and 200 mA forward current limits to ensure adequate headroom for the target circuit design.
Part Context
This component belongs to the Vishay BAT54 series of small signal Schottky diodes. The series includes single and dual configurations such as the BAT54 (single), BAT54A (common anode), and BAT54S (serial). The BAT54C specifically utilizes a common cathode arrangement, distinguishing it from other variants within the same family while sharing similar electrical performance metrics.
