BAS70-04

Nexperia · Schottky Diodes · SOT-23

BAS70-04 from Nexperia, in a SOT-23. 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 diode 1 of the dual Schottky diode, with its cathode-side connection made at pin 3 (K1).
2 K2 passive Cathode of diode 2 of the dual Schottky diode, with its anode-side connection made at pin 3 (A2).
3 K1; A2 passive Shared terminal: cathode of diode 1 and anode of diode 2, as listed in Table 2 of the datasheet.
