Total gate charge is 95 nC at 10 Vgs — the gate-driver must source this charge each switching cycle, so the switching frequency is limited by the driver's peak current and the gate-loop inductance. ## Thermal and voltage endurance Maximum power dissipation is 140 W — the actual continuous dissipation in a real board depends on the copper pad area under the TO-251 tab and the airflow across the leads. Gate-source voltage is limited to ±20 V absolute maximum; the gate drive should clamp transients below this to avoid oxide rupture.","metaTitle":"Infineon AUIRFU1010Z N-Channel MOSFET, 55V 42A TO-251","metaDescription":"AUIRFU1010Z N-channel MOSFET, 55 V drain-source, 42 A continuous drain current, 7.5 mOhm Rds(on).
