# IRFR5505TR

**UMW** · MOSFETs · TO-252

IRFR5505TR from UMW, 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 of the P-channel MOSFET; the gate-source voltage is rated ±20 V in the absolute maximum ratings. |
| 2 | D | passive | DRAIN; the part is rated for a drain-source voltage of -60 V and a continuous drain current of -10 A at VGS = -10 V, TC = 25°C. |
| 3 | S | passive | SOURCE; the reference terminal for the gate-source voltage, with the source current limited by the total power dissipation per note 5. |
