MCR16 from KY, in a SOT-23. 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 return terminal for on-state current (IT(RMS) 0.8 A, IT(AV) 0.7 A). |
| 2 | A | passive | Anode of the SCR, with repetitive peak off-state and reverse voltage VDRM/VRRM of 600 V. |
| 3 | G | input | Gate trigger input, with VGT ≤0.8 V and IGT ≤200 uA at VD=12 V, IT=0.1 A. |
