# IRFR420TRPBF-VB

**VBsemi Elec** · MOSFETs · TO-252

IRFR420TRPBF-VB from VBsemi Elec, 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 terminal; the gate-source voltage is rated at ±30 V (VGS) per the absolute maximum ratings. |
| 2 | D | passive | Drain terminal; the drain-source voltage is rated at 650 V with continuous drain current of 4.2 A at TC = 100 °C. |
| 3 | S | passive | Source terminal; the continuous source-drain diode current IS is rated at 4 A per the body diode characteristics. |
