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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | VBsemi Elec |+| Package | SO-8 |+| Category | Transistors/Thyristors |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `SI9926BDY-T1-E3-VB`++## CAD (KiCad official)++- Symbol: `SI9926BDY-T1-E3-VB`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [VBsemi Elec datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8603067729096699904) (None pp, sha256 `d73fb256a53213ce`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
