BAV99WT1G

onsemi · Switching Diodes · SOT-323

BAV99WT1G from onsemi, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ANODE passive Anode of diode 1 (D1). Diode D1 is connected between pin 1 (anode) and pin 3 (cathode). Rated 100 V reverse, 215 mA forward, Vf ~715 mV @ 1 mA.
2 CATHODE passive Cathode of diode 2 (D2). Diode D2 is connected between pin 3 (anode) and pin 2 (cathode). Rated 100 V reverse, 215 mA forward.
3 CATHODE/ANODE passive Common node: cathode of D1 and anode of D2 (series connection point). This is the shared middle terminal of the dual series diode configuration.

Provenance

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

  • Datasheet: onsemi datasheet (4 pp, sha256 3b8f1d0c907badc0, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
