# IRL540NSTRLPBF

**Infineon Technologies** · Global Sourcing Parts · D2PAK

IRL540NSTRLPBF from Infineon Technologies, in a D2PAK. 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; the gate-to-source voltage is rated at ±16 V maximum. |
| 2 | D | passive | Drain; rated for VDSS = 100 V and continuous drain current of 36 A at TC = 25°C, and also connected to the tab. |
| 3 | S | passive | Source; the power current return terminal of the HEXFET. |
