Zero trr — what it buys you in the switching loop
The Infineon BAS40-06B5000 is a Silicon Carbide Schottky diode in a common-anode pair, rated for 40 V reverse voltage and 120 mA average rectified current per diode. The headline spec is the zero reverse recovery time — no stored charge to sweep out when the diode turns off, which eliminates the switching loss and ringing you'd budget for with a standard PN or even a conventional Schottky.
PG-SOT23 footprint — board-level fit
Housed in a PG-SOT23 package (TO-236-3, SC-59, SOT-23-3), the common-anode pair shares the same three-pin footprint as a single SOT-23 transistor or diode. The cathode is the common node; the two anodes are the independent pins. Surface-mount assembly, no special pad geometry beyond the standard SOT-23 land pattern. Junction temperature rated to 150 °C, so it handles the self-heating from 120 mA DC without derating drama in a 85 °C ambient.
The BAS40-06B5000 is the Infineon prefix variant of the industry-standard BAS40-06; if you're already using the generic BAS40-06 in a common-anode Schottky position, this part is a drop-in replacement with the same electrical ratings and the same SOT-23 footprint.
