Temperature range and where it fits
Rated from -55°C to 150°C junction temperature, this part is specced for military, avionics, downhole, and under-hood automotive environments — not just office-temperature gear. That 150°C Tj max gives headroom when the part is dissipating its 2W maximum power in a warm enclosure or near a motor.
Gate charge and switching speed
Total gate charge is 34nC at 10V. That is moderate — the part can switch in the tens to low hundreds of kHz without a heroic gate driver. Input capacitance is 710pF at 25V drain bias, which is low enough that the Miller plateau is manageable for most PWM controllers.
Sourcing reality
There is no official replacement or second source listed in the Infineon catalog — the AUIRF7316QTR is the current production MPN. For dual-sourcing or a pin-compatible alternative, a buyer would need to evaluate a part on their own bench, as no factory cross-reference is published.
