STPS3150UY

STMicroelectronics · Schottky Barrier Diodes (SBD) · SMB

STPS3150UY from STMicroelectronics, in a SMB. 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 of the Schottky rectifier (marked K on the SMB package); the diode is rated for VRRM of 150 V and IF(AV) of 3 A.
2 A passive Anode of the Schottky rectifier (marked A on the SMB package); the diode is rated for IF(AV) of 3 A at TL = 130 °C.

  • Symbol: STPS3150UY
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: stps3150uy-etched.step / stps3150uy-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stps3150uy.step / stps3150uy.glb are the bare package body.
