BAT46WFILM

STMicroelectronics · Schottky Diodes · SOT-323

BAT46WFILM from STMicroelectronics, 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 A passive Diode anode. In SOT-323 single-diode configuration one of the two side pins is the anode; forward current flows into this pin toward the cathode (VF ~0.45 V at IF = 10 mA).
2 NC unconnected No internal connection. SOT-323 has three physical leads but the single-diode BAT46W only uses two of them; the middle pin on the two-lead side is unbonded.
3 K passive Diode cathode. Reverse leakage IR ≤ 2 µA at VR = 50 V (Tj = 25 °C); rated for 100 V repetitive peak reverse voltage.

  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: bat46wfilm-etched.step / bat46wfilm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat46wfilm.step / bat46wfilm.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (None pp, sha256 00aae2bac12854c9, retrieved 2026-08-17, 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).
