BAT42LS-QYL

Nexperia · Schottky Diodes · SOD-882

BAT42LS-QYL from Nexperia, in a SOD-882. 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 K passive Cathode, marked by the marking bar on the package; the device is rated for a reverse voltage VR ≤ 40 V and a forward current IF ≤ 200 mA.
2 A passive Anode of the Schottky diode, forming the forward-conduction terminal opposite the cathode (K).

CAD (KiCad official)

  • Symbol: BAT42LS-QYL
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: SOD-882 (KiCad packages3D, STEP)
  • 3D model files: bat42ls-qyl-etched.step / bat42ls-qyl-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat42ls-qyl.step / bat42ls-qyl.glb are the bare package body.
