KY · Thyristors (SCR)/Modules · SOT-23
BT169-23 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, pin 1 of the SOT-23 package (K(1) in the symbol). |
| 2 | A | passive | Anode of the SCR, pin 2 of the SOT-23 package (A(2) in the symbol); repetitive peak off-state/reverse voltage rating is 600V (BT169D). |
| 3 | G | input | Gate trigger input, pin 3 of the SOT-23 package (G(3) in the symbol); VGT ≤0.8V and IGT ≤200uA at VD=12V, IT=0.1A. |
