SI4850BDY-T1-GE3 from Vishay Intertech, in a SO-8. 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 | S | passive | Source. Tied internally to pins 2 and 3 (all source pins of the single N-channel MOSFET die). Continuous source-drain diode current 3.8 A at TC = 25 °C; body-diode VSD typ. 0.79 V at IS = 5 A. |
| 2 | S | passive | Source. Internally connected to pins 1 and 3 (common source of the N-channel MOSFET). |
| 3 | S | passive | Source. Internally connected to pins 1 and 2 (common source of the N-channel MOSFET). |
| 4 | G | input | Gate. Insulated MOSFET gate input. VGS max ±20 V; VGS(th) 1 V to 2.8 V (VDS = VGS, ID = 250 μA). Typical total gate charge Qg = 5.2 nC at VGS = 4.5 V, VDS = 30 V. Recommend series gate resistor for controlled switching (datasheet uses Rg = 1 Ω in switching tests). |
| 5 | D | passive | Drain. Internally connected to pins 6, 7 and 8 (common drain of the N-channel MOSFET die). VDS max 60 V; continuous drain current ID up to 11.3 A at TC = 25 °C; pulsed IDM 40 A. |
| 6 | D | passive | Drain. Internally connected to pins 5, 7 and 8 (common drain of the N-channel MOSFET). Multiple drain pins are provided to share current and improve thermal conduction through the drain lead-frame. |
| 7 | D | passive | Drain. Internally connected to pins 5, 6 and 8 (common drain of the N-channel MOSFET). |
| 8 | D | passive | Drain. Internally connected to pins 5, 6 and 7 (common drain of the N-channel MOSFET). The drain lead-frame acts as the primary thermal path; RthJF steady-state typ. 22 °C/W, max 28 °C/W. |
