The 50 A Id rating is the package-limited ceiling at Tc=25°C; real-world current depends on the heatsink and ambient — the TO-220FP's 30 W power dissipation ceiling is the practical constraint. ## 18 mOhm on-resistance — conduction loss at the operating point That is the conduction loss floor at the datasheet test point; actual on-resistance rises with junction temperature — expect roughly 1.5× the 25°C value at 125°C Tj. For a 20 A load, I²R loss at 25°C is about 7.2 W, which the TO-220FP's 30 W dissipation limit can handle with a modest heatsink. ## Gate charge and switching — 60 nC at 10 V Total gate charge is 60 nC at Vgs=10 V. That is moderate for a 50 A-class MOSFET — the gate driver needs to source and sink that charge each switching cycle. ## TO-220 Full Pack — isolated tab saves assembly steps The TO-220FP (Full Pack) package has a fully molded plastic body that isolates the mounting tab from the drain. Through-hole mounting suits point-of-load boards and power supplies where wave-solder assembly is the norm. The 175°C maximum exceeds the typical 150°C industrial ceiling, giving extra thermal headroom for high-ambient environments like motor drives inside sealed enclosures or power stages near hot surfaces.
