SLVU2.8-4BTG

Littelfuse · ESD And Surge Protection (TVS/ESD) · SOIC-8

SLVU2.8-4BTG from Littelfuse, in a SOIC-8. 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 1 passive One terminal of the protected line pair 1.3; the datasheet's pinout diagram labels it only as 'Pin 1.3' and gives no separate function name.
2 2 passive One terminal of the protected line pair 2.4; the datasheet's pinout diagram labels it only as 'Pin 2.4' and gives no separate function name.
3 3 passive The other terminal of the protected line pair 1.3; the datasheet's pinout diagram labels it only as 'Pin 1.3' and gives no separate function name.
4 4 passive The other terminal of the protected line pair 2.4; the datasheet's pinout diagram labels it only as 'Pin 2.4' and gives no separate function name.
5 5 passive One terminal of the protected line pair 5.7; the datasheet's pinout diagram labels it only as 'Pin 5.7' and gives no separate function name.
6 6 passive One terminal of the protected line pair 6.8; the datasheet's pinout diagram labels it only as 'Pin 6.8' and gives no separate function name.
7 7 passive The other terminal of the protected line pair 5.7; the datasheet's pinout diagram labels it only as 'Pin 5.7' and gives no separate function name.
8 8 passive The other terminal of the protected line pair 6.8; the datasheet's pinout diagram labels it only as 'Pin 6.8' and gives no separate function name.

CAD (KiCad official)

  • Symbol: SLVU2.8-4BTG
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: slvu2-8-4btg-etched.step / slvu2-8-4btg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); slvu2-8-4btg.step / slvu2-8-4btg.glb are the bare package body.
