P6SMBJ78A

PANJIT International · ESD Protection Devices · SMB(DO-214AA)

P6SMBJ78A from PANJIT International, 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, the end marked by the color band; for the unidirectional P6SMBJ78A this is the terminal that goes positive relative to the anode, with VRWM 78 V, breakdown 86.7 to 95.8 V at 1 mA, and max clamp 126 V at 4.7 A (10/1000μs).
2 A passive Anode, the terminal opposite the color band; the 600 W (10/1000μs) transient suppressor conducts forward from here to the cathode, with a peak forward surge current of 100 A (8.3 ms half sine).

CAD (KiCad official)

  • Symbol: P6SMBJ78A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: p6smbj78a-etched.step / p6smbj78a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p6smbj78a.step / p6smbj78a.glb are the bare package body.
