NTH4L070N120M3S

onsemi · Silicon Carbide Field Effect Transistor (MOSFET) · TO-247-4L

NTH4L070N120M3S from onsemi, in a TO-247-4L. 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.
