VBPW34S

Vishay Semiconductors · Photodiodes · SMD, 4.4x3.9mm

VBPW34S from Vishay Semiconductors, in a SMD, 4.4x3.9mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). The symbol is generated from that pin table and the footprint is an Adom_Gen land derived from the manufacturer drawing; the 3D model is generated to fit it.

Pinout

Pin Name Type Function
1 Cathode passive Cathode: the plain 1.6 mm lead (right in the p.4 top view), facing the sprocket holes on the p.6 tape ('CATHODE'). Number by convention; Vishay prints none.
2 Anode passive Anode: the lead necked to 0.8 mm at its tip (left in the p.4 top view).

CAD (Adom-generated)

  • Symbol: VBPW34S
  • Footprint: Adom_Gen:Vishay_Semiconductors_VBPW34_f42b60
  • 3D model: generated to fit the land (STEP)
  • 3D model files: vbpw34s-etched.step / vbpw34s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); vbpw34s.step / vbpw34s.glb are the bare package body.

Provenance

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

  • Datasheet: Vishay Semiconductors datasheet (8 pp, sha256 33e4449b278380d4, retrieved 2026-11-10, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: symbol generated from the datasheet pin table; footprint an Adom_Gen land derived from the manufacturer drawing. 3D model generated to fit that land.
