BZW50-39

STMicroelectronics · TVS · R6

BZW50-39 from STMicroelectronics, in a R6. 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 Anode terminal of the unidirectional TVS diode. In the R6 axial package this is one of the two leads; the cathode is identified by the cathode bar marking on the body.
2 K passive Cathode terminal of the unidirectional TVS diode. Identified by the printed cathode bar on the body (unidirectional devices only, per Figure 14 marking layout).

CAD (KiCad official)

  • Symbol: BZW50-39
  • Footprint: Resistor_THT:R_Array_SIP6
  • 3D model: R6 (KiCad packages3D, STEP)
  • 3D model files: bzw50-39-etched.step / bzw50-39-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bzw50-39.step / bzw50-39.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (12 pp, sha256 e556076e948a7910, retrieved 2026-08-17, tier: manufacturer)
  • 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).
