75 V, 195 A — the conduction-loss floor for high-current switching
The IRFS7730TRLPBF is an N-channel MOSFET from Infineon's HEXFET and StrongIRFET series, built for applications where the rail voltage sits at 75 V and the continuous drain current reaches 195 A at the case.
Gate charge and the driver it demands
The 407 nC total gate charge at 10 V determines the gate-drive requirement. The 13660 pF input capacitance at 25 V drain-source reinforces the same point: the driver sees a large capacitive load at the gate.
Package and thermal path
The D²PAK surface-mount package with the exposed tab is the thermal bottleneck. A two-layer board with a minimal copper pour will hit the thermal limit well before the 375 W case rating suggests.
