P6SMB350CA

Littelfuse · TVS · DO-214AA

P6SMB350CA from Littelfuse, in a 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 Terminal 1 passive First terminal of the bidirectional TVS (CA suffix, no cathode band), which clamps transients of either polarity, with VR 300 V and VBR 332-368 V at 1 mA.
2 Terminal 2 passive Second terminal of the bidirectional TVS, interchangeable with terminal 1, with maximum clamping voltage 482 V at 1.7 A peak pulse current.

CAD (KiCad official)

  • Symbol: P6SMB350CA
  • Footprint: Diode_SMD:D_SMB
  • 3D model: DO-214AA (KiCad packages3D, STEP)
  • 3D model files: p6smb350ca-etched.step / p6smb350ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p6smb350ca.step / p6smb350ca.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Littelfuse datasheet (6 pp, sha256 2c321de35bbafba1, retrieved 2026-10-22, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
