1SMA5956B

YFW · Zener Diodes · DO-214AC(SMA)

1SMA5956B from YFW, in a DO-214AC(SMA). 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 Cathode passive Cathode terminal of the zener diode, marked as pin 1 in the DO-214AC/SMA pinning diagram; the datasheet gives no pin-specific electrical limits beyond the device ratings (PD 1.5 W, Tj -55 to +150 °C).
2 Anode passive Anode terminal of the zener diode, marked as pin 2 in the DO-214AC/SMA pinning diagram; the datasheet gives no pin-specific electrical limits beyond the device ratings (PD 1.5 W, Tj -55 to +150 °C).

  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: 1sma5956b-etched.step / 1sma5956b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 1sma5956b.step / 1sma5956b.glb are the bare package body.

Provenance

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

  • Datasheet: YFW datasheet (3 pp, sha256 f0e7523067927399, retrieved 2026-10-30, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
