BAS70Q

Yangzhou Yangjie Elec Tech · Schottky Barrier Diodes (SBD) · SOT-23(TO-236)

BAS70Q from Yangzhou Yangjie Elec Tech, in a SOT-23(TO-236). 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 A passive Anode of the single Schottky diode (VR 70V, IFAV 70mA, IFSM 100mA at t=8.3ms).
2 NC unconnected No internal connection in the single-diode BAS70Q; the pin 1 and pin 3 diode is the only element shown in the package diagram.
3 K passive Cathode of the single Schottky diode (VR 70V, IFAV 70mA, forward voltage max 0.41V at IF=1mA).
