Product Overview
BAS40-04,215 is a Nexperia dual Schottky diode with the two junctions connected in series inside a three-pin SOT-23 package. It is intended for high-speed switching and voltage-clamping functions that benefit from low junction capacitance and Schottky forward behavior.
The -04 topology is electrically different from independent, common-anode and common-cathode BAS40 variants even though their basic diode ratings are similar.
