RB705DT146

ROHM Semicon · Schottky Barrier Diodes (SBD) · TO-236-3(SOT-23-3)

RB705DT146 from ROHM Semicon, in a TO-236-3(SOT-23-3). 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 A1 passive Anode of one Schottky diode (VR 40 V, Io 30 mA per diode, IFSM 0.2 A).
2 A2 passive Anode of the second Schottky diode (VR 40 V, Io 30 mA per diode, IFSM 0.2 A).
3 K passive Common cathode of both Schottky diodes (VR 40 V, VF max 0.37 V at IF=1 mA).
