NTD4906NAT4G-VB from VBsemi Elec, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate. MOSFET control terminal. Absolute maximum VGS = ±20 V. Threshold voltage VGS(th) = 1.5-2.5 V (typ. ~2 V at ID = 250 µA). Gate resistance Rg typ. 1.4 Ω, total gate charge Qg typ. 151 nC at VGS = 10 V. |
| 2 | D | passive | Drain. High-current power terminal, also electrically connected to the tab of the TO-252 package for heatsinking. Drain-Source breakdown voltage VDS ≥ 30 V. Continuous drain current ID up to 100 A at TC = 25 °C (package limited to 90 A). RDS(on) typ. 0.002 Ω at VGS = 10 V. |
| 3 | S | passive | Source. Low-side power terminal / current return of the N-channel MOSFET. Also serves as anode reference of the intrinsic body diode (VSD typ. 0.8 V at IS = 22 A). Continuous source-drain diode current IS up to 90 A at TC = 25 °C. |
