SMP75-8

STMicroelectronics · Semiconductor Discharge Tubes (TSS) · SMB

SMP75-8 from STMicroelectronics, 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 A1 passive Bidirectional crowbar protection terminal 1 (top terminal in Figure 1), interchangeable with terminal 2, with 8 V voltage rating, IR = 2 µA max leakage and IH = 150 mA min holding current.
2 A2 passive Bidirectional crowbar protection terminal 2 (bottom terminal in Figure 1), interchangeable with terminal 1, with repetitive peak pulse current IPP = 75 A (10/1000 µs).

CAD (KiCad official)

  • Symbol: SMP75-8
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: smp75-8-etched.step / smp75-8-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smp75-8.step / smp75-8.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (9 pp, sha256 f3a5d1c1f3422159, retrieved 2026-10-26, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
