KTP · MOSFETs · TO-252
FQD2N65SE 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 | Gate | input | Gate terminal of the 650V N-channel MOSFET, with gate-source voltage rated at ±30 V (VGSS absolute maximum). |
| 2 | Drain | passive | Drain terminal, rated for 650 V drain-source voltage (VDSS) and 2 A drain current at TC=25℃ (1.5 A at TC=100℃). |
| 3 | Source | passive | Source terminal, the reference for the gate-source rating (±30 V) and the diode forward current rating (IS max 2 A). |
