FH2045D
XIN FEI HONG · MOSFETs · TO-252
FH2045D from XIN FEI HONG, 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 | G | input | Gate; capable of 2.5V gate drive, with VGS rated at ±12V maximum and a gate threshold of 0.6 to 0.9V at ID=1mA. |
| 2 | D | passive | Drain, also connected to the exposed mounting tab; VDS is rated at 20V, with 80A continuous (package limited) and 160A pulsed drain current. |
| 3 | S | passive | Source; the body diode has a forward voltage of 1.2V maximum at IS=2.5A. |
