CI30S120D3 from Tokmas, in a TO-247-3. 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 | A1 | passive | Anode of the first diode leg (per-leg IF 15 A at TC=152°C, VRRM 1200 V), with its cathode common to pin 2 and the case. |
| 2 | K | passive | Common cathode of both diode legs, connected internally to the case/tab (VRRM 1200 V, device IF 30 A at TC=152°C). |
| 3 | A2 | passive | Anode of the second diode leg (per-leg IF 15 A at TC=152°C, VRRM 1200 V), with its cathode common to pin 2 and the case. |
