# BMB65N380E1

**Bestirpower** · MOSFETs · TO-263-2L

BMB65N380E1 from Bestirpower, in a TO-263-2L. 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; gate-to-source voltage is rated at ±30 V maximum, with a threshold of 2.5 to 4.5 V at VGS = VDS and ID = 0.8 mA. |
| 2 | D | passive | Drain (also the exposed tab); drain-to-source voltage is rated at 650 V with 9.6 A continuous drain current at TC = 25℃. |
| 3 | S | passive | Source; carries the 9.6 A continuous drain current and the body-diode current (maximum 9.6 A continuous, 28.8 A pulsed). |
