KSMAJ14A-E3

KUU · TVS · SMA

KSMAJ14A-E3 from KUU, in a SMA. 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 color band on the unidirectional KSMAJ14A; connect to the protected line (VRWM 14 V, breakdown 15.60-17.20 V at 1 mA, clamping 23.2 V at 17.2 A).
2 A passive Anode, the terminal opposite the color band; connect to ground/return for the unidirectional KSMAJ14A (400 W peak pulse power on 10/1000μs).

CAD (KiCad official)

  • Symbol: KSMAJ14A-E3
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: ksmaj14a-e3-etched.step / ksmaj14a-e3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ksmaj14a-e3.step / ksmaj14a-e3.glb are the bare package body.
