KBU3510

Yangzhou Yangjie Elec Tech · Bridge Rectifiers · KBU

KBU3510 from Yangzhou Yangjie Elec Tech, in a KBU. 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 - passive DC negative output of the bridge, marked '-' on the KBU outline drawing, for a bridge rated at 35 A average output (IO at Tc=115 °C).
2 AC passive AC input of the bridge, marked 'AC' on the KBU outline drawing, for a bridge rated at VRRM up to 1000 V (KBU3510).
3 AC passive Second AC input of the bridge, marked 'AC' on the KBU outline drawing, for a bridge rated at VRRM up to 1000 V (KBU3510).
4 + passive DC positive output of the bridge, marked '+' on the KBU outline drawing, for a bridge rated at 35 A average output (IO at Tc=115 °C).

CAD (KiCad official)

  • Symbol: KBU3510
  • Footprint: Diode_THT:Diode_Bridge_Vishay_KBU
  • 3D model: KBU (KiCad packages3D, STEP)
  • 3D model files: kbu3510-etched.step / kbu3510-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kbu3510.step / kbu3510.glb are the bare package body.

Provenance

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

  • Datasheet: Yangzhou Yangjie Elec Tech datasheet (4 pp, sha256 a585e5871790aa9c, retrieved 2026-10-21, 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).
