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 | Driver Source (Kelvin source). Low-inductance source reference used by the gate driver only; carries only gate-loop return current, not the main drain current. Improves switching performance by decoupling driver return from power-source parasitic inductance. |+| 2 | G | input | Gate. Controls the MOSFET channel. Recommended V_GS operating range −3 V to +18 V; absolute max V_GS = −10 V / +22 V. Typical V_GS(th) = 2.9 V (I_D = 7 mA). Total gate charge Q_G(tot) ≈ 57 nC at V_GS = −3/+18 V, V_DS = 800 V. |+| 3 | D | passive | Drain. V_DSS = 1200 V (breakdown); continuous I_D = 34 A at T_C = 25 °C (24 A at T_C = 100 °C); pulsed I_DM = 98 A. Also connected to the metal mounting tab of the TO-247-4L package. |+| 4 | S2 | passive | Power Source. Main source lead that carries the drain-to-source load current back to the power-loop return. Integral body diode (source-to-drain) has V_SD ≈ 4.7 V typ at I_SD = 15 A, V_GS = −3 V; continuous I_S = 31 A. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | TO-247-4L |+| Category | Silicon Carbide (SiC) Devices |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `NTH4L070N120M3S`++## CAD (KiCad official)++- Symbol: `NTH4L070N120M3S`+- Footprint: `Package_TO_SOT_THT:TO-247-4_Vertical`+- 3D model: TO-247-4L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8602734235388702720) (8 pp, sha256 `bd736a1bc627d172`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
