Product details

The ±20 V gate-source maximum and 4 V threshold at 250 µA mean a 10 V gate drive is the intended operating point; a logic-level 5 V drive will not fully enhance the channel, so plan for a driver that swings to 10 V.

Obsolete — plan your BOM move now

ST officially lists the STP14NF10 as Obsolete. There is no registered successor order code in the ST portfolio. STP100N10F7 or similar 100 V, 15 A class parts) for a current-production alternative; pin compatibility and footprint should be verified against the TO-220 case.

Thermal and switching margins

Maximum power dissipation is 60 W at case temperature, derated above 25°C per the thermal curve. Input capacitance of 460 pF at 25 V drain-source means the Miller plateau is short; still, a series gate resistor in the 10 Ω to 47 Ω range helps control ringing on fast edges.

Frequently asked questions

Is STP14NF10 obsolete?

Yes, ST officially lists the STP14NF10 as Obsolete. No direct-replacement successor is registered; for new production, evaluate current 100 V / 15 A N-channel MOSFETs from ST's STripFET F7 or V families, verifying footprint and gate drive compatibility.
