BAS70

hongjiacheng · Schottky Diodes · SOT-23

BAS70 from hongjiacheng, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A passive Anode of the Schottky barrier diode. Forward current flows from anode (pin 1) to cathode (pin 3). Max forward voltage 410 mV at IF = 1 mA, 1000 mV at IF = 15 mA.
2 NC unconnected No internal connection on the single BAS70 variant in SOT-23. Left floating on the die; may be tied to the anode or cathode on the PCB to improve heat sinking.
3 K passive Cathode of the Schottky barrier diode. Denoted by the cathode line marking on the package. Reverse breakdown 70 V; reverse leakage IR < 0.2 µA at VR = 50 V.
