SM6T150A

STMicroelectronics · TVS · SMB(DO-214AA)

SM6T150A from STMicroelectronics, in a SMB(DO-214AA). 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 band on unidirectional SM6T150A devices (stand-off voltage VRM 128 V, breakdown VBR 143-158 V at 1 mA).
2 A passive Anode of the unidirectional SM6T150A TVS diode, which clamps at max 207 V at 2.9 A (10/1000 µs).

CAD (KiCad official)

  • Symbol: SM6T150A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: sm6t150a-etched.step / sm6t150a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm6t150a.step / sm6t150a.glb are the bare package body.
