Gate charge is 14 nC at 10 V. ## 175 °C junction — thermal headroom for tight enclosures This gives extra margin in high-ambient environments such as under-hood automotive or sealed power supplies where the case temperature can climb. Maximum power dissipation is 38 W at case temperature Tc. The TO-251 package's exposed tab must be soldered to a sufficient copper area on the PCB to keep the junction below the 175 °C limit under sustained load. ## Gate drive and switching profile The device is specified for gate drive voltages of 4.5 V and 10 V, with the 10.5 mOhm Rds(on) achieved at 10 V. At 4.5 V the on-resistance will be higher. Maximum gate-source voltage is ±20 V. Input capacitance Ciss is 1500 pF typical at 15 V drain-source. Combined with the 14 nC gate charge, the gate driver sees a moderate capacitive load. ## Active production, ROHS3 compliant It is ROHS3 compliant.","metaTitle":"Infineon IPS105N03LG N-Channel MOSFET, 30V, 35A, TO-251","metaDescription":"Infineon IPS105N03LG CoolMOS N-channel MOSFET, 30V Vdss, 35A Id, 10.5mOhm Rds(on).
