MBR120ESFT1G

Tokmas · Schottky Barrier Diodes (SBD) · SOD-123FL

MBR120ESFT1G from Tokmas, in a SOD-123FL. 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 K passive Cathode, identified by the cathode band polarity designator on the package; the diode blocks up to 20 V DC reverse voltage (VR).
2 A passive Anode; the diode conducts up to 1.0 A average rectified forward current (IO) at TL = 140°C.
