# SI3455ADV-T1-GE3-VB

**VBsemi Elec** · MOSFETs · TSOP-6

SI3455ADV-T1-GE3-VB from VBsemi Elec, in a TSOP-6. 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 | D | passive | Drain. Pins 1, 2, 5, and 6 are internally connected together as the MOSFET drain. Drain-source breakdown voltage VDS = -30 V; continuous ID = -4.8 A at TC = 25 °C. |
| 2 | D | passive | Drain. Internally tied to pins 1, 5, and 6 (MOSFET drain). |
| 3 | G | input | Gate. Gate-source voltage rating VGS = ±20 V; typical VGS(th) between -0.5 V and -2.0 V (VDS = VGS, ID = -250 µA). Total gate charge Qg ≈ 5.1 nC at VGS = -4.5 V. |
| 4 | S | passive | Source. Reference terminal for VGS and body-diode anode (P-channel: source-to-drain body diode conducts when VSD > ~0.8 V, IS,cont = -2.5 A at TC = 25 °C). |
| 5 | D | passive | Drain. Internally tied to pins 1, 2, and 6 (MOSFET drain). |
| 6 | D | passive | Drain. Internally tied to pins 1, 2, and 5 (MOSFET drain). |
