X0202MA 1BA2

STMicroelectronics · Thyristors (SCR)/Modules · TO-92

X0202MA 1BA2 from STMicroelectronics, in a TO-92. 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 K passive Cathode terminal of the sensitive-gate SCR; carries the on-state current in the reverse-return path and is the reference terminal for the gate trigger voltage/current (VGT max 0.8 V, IGT max 200 µA for the X0202 grade).
2 A passive Anode terminal of the SCR; conducts the on-state current (IT(RMS) = 1.25 A rms, IT(AV) = 0.8 A average, 180° conduction) and blocks the repetitive peak off-state/reverse voltage of 600 V (M grade) when the device is off.
3 G input Gate trigger input; injecting a current of 20 µA min / 200 µA max at a gate-to-cathode voltage VGT of 0.8 V max (X0202 grade) latches the SCR into conduction between anode and cathode.

CAD (KiCad official)

  • Symbol: X0202MA 1BA2
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: x0202ma-1ba2-etched.step / x0202ma-1ba2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); x0202ma-1ba2.step / x0202ma-1ba2.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (11 pp, sha256 0ef7fc80b539119a, retrieved 2026-09-29, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
