P0102DA 1AA3

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

P0102DA 1AA3 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 of the SCR; the on-state current (IT(RMS) 0.8 A max) leaves the device here.
2 G input Gate trigger input; IGT max 200 µA and VGT max 0.8 V at VD = 12 V, RL = 33 Ω, with peak gate current IGM of 1 A for tp = 20 µs.
3 A passive Anode of the SCR; blocks a repetitive peak off-state voltage VDRM/VRRM of 400 V.

CAD (KiCad official)

  • Symbol: P0102DA 1AA3
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: p0102da-1aa3-etched.step / p0102da-1aa3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p0102da-1aa3.step / p0102da-1aa3.glb are the bare package body.
