55 V N-channel in a D-Pak — what it handles
It comes in a surface-mount D-Pak (TO-252) package, which keeps the board footprint small while the tab carries the drain current and sinks heat to the PCB copper. Gate charge is only 15 nC at 5 V, so a logic-level microcontroller pin or a small gate driver can switch it without a bulky driver stage.
Gate drive and switching — 5 V logic works
The 2 V threshold at 250 µA confirms it starts conducting well below 5 V, so yes, you can use it with 5 V gate drive for moderate currents. Input capacitance is 480 pF at 25 V drain-source — low enough that the gate driver does not need to sink much charge per cycle. The 15 nC total gate charge at 5 V means a 100 mA driver can switch it at tens of kHz without thermal stress on the driver.
Temperature range — wider than industrial
Junction temperature range is -55°C to 175°C, which covers industrial, automotive under-hood, and military-adjacent environments. The 45 W maximum power dissipation at case temperature is the thermal limit; real-world dissipation depends on the PCB copper area under the D-Pak tab.
