The 180 MHz transition frequency means it can handle switching in the low-MHz range without excessive switching loss. ## Thermal and saturation performance for real loads Maximum power dissipation is 2.5 W — in a SOT-223 footprint, that demands a decent copper area on the PCB to keep the junction below the 150°C absolute maximum. The Vce saturation voltage is specified at 330 mV max with a 50 mA base drive and 5 A collector current, so conduction loss at full load is about 1.65 W — within the 2.5 W budget if the board can sink the heat.
