SI9926BDY-T1-E3-VB from VBsemi Elec, 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 | S1 | passive | Source of N-channel MOSFET #1. Continuous source current (diode conduction) rated 1.7 A. Typically tied to circuit ground or the low side of the switched load. |
| 2 | G1 | input | Gate of N-channel MOSFET #1. VGS absolute maximum ± 12 V; VGS(th) = 0.6-1.5 V at ID = 250 µA. Drive with 4.5 V for full enhancement (RDS(on) = 0.019 Ω). |
| 3 | S2 | passive | Source of N-channel MOSFET #2. Continuous source current (diode conduction) rated 1.7 A. Independent from MOSFET #1's source. |
| 4 | G2 | input | Gate of N-channel MOSFET #2. VGS absolute maximum ± 12 V; VGS(th) = 0.6-1.5 V at ID = 250 µA. Drive with 4.5 V for full enhancement (RDS(on) = 0.019 Ω). |
| 5 | D2 | passive | Drain of N-channel MOSFET #2 (pin 5 and pin 6 are both D2, internally connected for current handling/thermal). VDS max 20 V; continuous ID = 7.1 A at TA = 25 °C. |
| 6 | D2 | passive | Drain of N-channel MOSFET #2 (pin 5 and pin 6 are both D2, internally connected for current handling/thermal). VDS max 20 V; continuous ID = 7.1 A at TA = 25 °C. |
| 7 | D1 | passive | Drain of N-channel MOSFET #1 (pin 7 and pin 8 are both D1, internally connected for current handling/thermal). VDS max 20 V; continuous ID = 7.1 A at TA = 25 °C. |
| 8 | D1 | passive | Drain of N-channel MOSFET #1 (pin 7 and pin 8 are both D1, internally connected for current handling/thermal). VDS max 20 V; continuous ID = 7.1 A at TA = 25 °C. |
