The DPAK (TO-252) surface-mount package lets the PCB copper area serve as the primary heatsink; the exposed tab is the drain connection.
Junction temperature range and environment
The 175°C max is common for automotive-grade power MOSFETs; the -55°C floor covers cold-crank and outdoor telecom cabinet scenarios.
The specified drive voltage for achieving the minimum Rds(on) is 10 V; the maximum gate-source voltage is ±20 V. The 2600 pF input capacitance at 30 V drain-source gives a rough idea of the driver current needed for a given rise time.
The tab is soldered to the PCB pad for both electrical connection and thermal dissipation. The supplier device package is DPAK.
