**VBsemi Elec** · MOSFETs · TO-252

SUD20N10-66L-T1-GE3-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. Insulated gate terminal controlling drain-source channel conduction. Absolute maximum VGS = ±20 V; typical VGS(th) = 1.0-3.5 V; drive at VGS = 10 V for full enhancement (RDS(on) = 0.114 Ω typ). |
| 2 | D | passive | Drain. Also electrically connected to the exposed tab of the TO-252 package for thermal dissipation. Rated VDS = 100 V, ID = 15 A continuous (TC = 25 °C), pulsed IDM = 40 A. |
| 3 | S | passive | Source. Reference terminal for the MOSFET; internal body diode anode with VSD = 0.9 V typ at IF = 3 A. Continuous source (diode conduction) current IS = 3 A. |
| 4 | D (Tab) | passive | Exposed thermal tab, internally connected to Drain. Provides low junction-to-case thermal resistance (RthJC = 0.85 °C/W typ) and is intended to be soldered to a copper heatsink pad. |
