X0405S-KTP
KTP · Thyristors (SCR)/Modules · TO-252
X0405S-KTP from KTP, in a TO-252. 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 (K(1)) of the sensitive-gate SCR, the load-current return terminal; device is rated 600V VDRM/VRRM and 4A IT(RMS). |
| 2 | A | passive | Anode (A(2)) of the SCR, also the tab; rated 600V repetitive peak off-state/reverse voltage and 4.0A RMS on-state current. |
| 3 | G | input | Gate (G(3)) trigger input; IGT max 200µA and VGT max 0.8V at VD=12V, peak gate current 1.2A, average gate power 0.2W. |
