P0111MA 1AA3

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

P0111MA 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 first lead labelled K on the TO-92 (P011xxA) drawing; IT(RMS) up to 0.8 A.
2 G input Gate trigger input, the middle lead of the TO-92; IGT is 4 µA min to 25 µA max at VD = 12 V, RL = 140 Ω, and VGT is 0.8 V max.
3 A passive Anode of the SCR, the third lead labelled A on the TO-92 drawing; VDRM/VRRM is 600 V for the P0111M.
