GBU15J

LRC · Bridge Rectifiers · GBU

GBU15J from LRC, in a GBU. 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 - power_out DC negative output of the bridge, marked "−" on the package body; the datasheet rates average rectified output current of 15 A at Tc=100℃.
2 AC1 passive AC input terminal marked "~"; the datasheet rates VRMS of 420 V for GBU15J.
3 AC2 passive AC input terminal marked "~"; the datasheet rates VRMS of 420 V for GBU15J.
4 + power_out DC positive output of the bridge, marked "+" on the package body; the datasheet rates VRRM of 600 V for GBU15J.

CAD (KiCad official)

  • Symbol: GBU15J
  • Footprint: Diode_THT:Diode_Bridge_Vishay_GBU
  • 3D model: GBU (KiCad packages3D, STEP)
  • 3D model files: gbu15j-etched.step / gbu15j-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gbu15j.step / gbu15j.glb are the bare package body.

Provenance

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

  • Datasheet: LRC datasheet (3 pp, sha256 8e2dc0a0823d24dc, retrieved 2026-10-21, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
