BAS70WT-04

Yangzhou Yangjie Elec Tech · Schottky Diodes · SOT-323(SC-70)

BAS70WT-04 from Yangzhou Yangjie Elec Tech, in a SOT-323(SC-70). 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 Diode 1 terminal on pin 1 of the BAS70WT-04 dual Schottky diode (70 V VR, 70 mA IF per diode); polarity per the package symbol on page 1.
2 K2 passive Diode 2 terminal on pin 2 of the BAS70WT-04 dual Schottky diode (70 V VR, 70 mA IF per diode); polarity per the package symbol on page 1.
3 COMMON passive Common node of the two Schottky diodes in the BAS70WT-04, joining the two diodes and brought out on the single top lead of the SOT-323.

CAD (KiCad official)

  • Symbol: BAS70WT-04
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323(SC-70) (KiCad packages3D, STEP)
  • 3D model files: bas70wt-04-etched.step / bas70wt-04-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas70wt-04.step / bas70wt-04.glb are the bare package body.
