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. |
