5KASMC30AHM3_A

Vishay Intertech · TVS · SMC(DO-214AB)

5KASMC30AHM3_A from Vishay Intertech, in a SMC(DO-214AB). 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, the end marked by the color band; uni-directional TVS that is reverse-biased in normal operation, with stand-off voltage VWM of 30 V and breakdown VBR of 33.3 V to 36.8 V for the 5KASMC30A.
2 A passive Anode terminal of the uni-directional TVS diode, connected to the lower potential or ground side of the protected line.

CAD (KiCad official)

  • Symbol: 5KASMC30AHM3_A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: 5kasmc30ahm3-a-etched.step / 5kasmc30ahm3-a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 5kasmc30ahm3-a.step / 5kasmc30ahm3-a.glb are the bare package body.
