Input capacitance is 2500 pF at 50 V drain-source. The gate threshold voltage maximum is 3.5 V at 46 µA drain current, and the recommended drive voltage range for minimum and maximum Rds(on) is 6 V to 10 V. For a 100 kHz hard-switched application, the 35 nC Qg keeps gate-drive losses manageable with a standard driver IC.
The OptiMOS series is Infineon's mainstream power MOSFET platform, with broad distribution support.
Maximum on-resistance is 12.2 mOhm at 46 A drain current with 10 V gate drive. This is the figure to use for conduction loss calculations at full load.
Yes, it is ROHS3 compliant, meeting current EU RoHS exemption rules.
At 94 W maximum power dissipation, a heatsink or substantial PCB copper area on the drain tab is required for continuous high-current operation. The exact need depends on load current, switching frequency, and ambient temperature — the junction temperature must stay within the -55°C to 175°C range.
The IPD50R950CEAUMA1 is a different voltage class (500 V) and current rating (4.3 A), not a functional equivalent. For a 100 V, 59 A N-channel MOSFET in TO-252, the IPD122N10N3GATMA1 is the active OptiMOS option; Infineon does not list a direct pin-compatible second source in this series.
