Product details

500 V N-channel MOSFET with automotive qualification

The STD14NM50NAG: The 320 mOhm maximum on-resistance at 6 A, 10 V gate drive defines the conduction loss for a typical switching application. AEC-Q101 qualification confirms suitability for automotive power-train, DC-DC converter, and PFC stages where reliability screening is required.

The device requires a 10 V gate drive for the specified on-resistance; the maximum gate threshold voltage is 4 V at 250 µA drain current. Total gate charge is 27 nC at 10 V, and input capacitance is 816 pF at 50 V drain-source, giving the design engineer a clear budget for gate-drive sizing and switching loss estimation.

The junction temperature rating is 150 °C.
