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.
