Low-loss 40V power switch for high-current rails
The IRFS7430TRL7PP is an N-channel MOSFET from Infineon's HEXFET® and StrongIRFET™ series, designed for low-voltage, high-current switching applications where conduction losses dominate the thermal budget.
Gate drive and switching considerations
Input capacitance (Ciss) is 13975 pF at 25 V drain-source; this large input capacitance sets the switching losses and the driver's average current draw at the operating frequency. The drive voltage range is 6 V to 10 V for achieving the specified Rds(on); operating at 6 V increases on-resistance above the datasheet minimum, so 10 V drive is recommended for full performance.
