# UF5305L-TN3-T-VB

**VBsemi Elec** · MOSFETs · TO-252

UF5305L-TN3-T-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 MOSFET control terminal; VGS(th) = -1.5 V to -3 V, VGS absolute maximum ±20 V. Drives the P-channel to enhance conduction between source and drain when pulled negative relative to source. |
| 2 | D | passive | Drain. Power terminal; VDS rating -60 V, continuous ID = -50 A at TC = 25 °C, RDS(on) = 0.020 Ω at VGS = -10 V. On a TO-252 the drain is also electrically connected to the tab (pin 4). |
| 3 | S | passive | Source. Return terminal for load current; body-diode anode. Continuous source current -40 A, forward voltage VSD = -1 V typ (VSD = -1.6 V max) at IF = -40 A. |
| 4 | D | passive | Drain tab. Large exposed metal tab of the TO-252 (DPAK) package; electrically identical to pin 2 (drain) and provides the primary thermal path (RthJC = 0.82 °C/W typ). |
