PANJIT International · Schottky Barrier Diodes (SBD) · SOD-523

RB520S40_R1_00001 from PANJIT International, in a SOD-523. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Cathode passive Cathode terminal of the Schottky diode (pin 1 in the package drawing); 40 V peak repetitive reverse voltage (VRRM) and 250 mA forward continuous current.
2 Anode passive Anode terminal of the Schottky diode (pin 2 in the package drawing); forward voltage drop of 0.37 V typ at IF=20mA with a 0.6 V maximum at IF=200mA.
