TPSMBJ12A

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SMB

TPSMBJ12A from TECH PUBLIC, 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 Cathode passive Cathode terminal marked by the cathode band on the SMB body; the unidirectional TPSMBJ12A has a 12 V reverse stand-off voltage (VR), 13.30-14.70 V breakdown at 1 mA, and clamps at 19.9 V max at 30.2 A peak pulse current.
2 Anode passive Anode terminal at the end opposite the cathode band; the unidirectional TPSMBJ12A is rated for 600 W minimum peak pulse power on a 10/1000 us waveform.

  • Symbol: TPSMBJ12A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: tpsmbj12a-etched.step / tpsmbj12a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpsmbj12a.step / tpsmbj12a.glb are the bare package body.
