The through-hole mounting suits wave-solder assembly on a single-sided or double-sided PCB. Maximum power dissipation is 35 W at the case, which means a heatsink with adequate thermal resistance is required for any load above a few amps continuous. ## Switching loss and gate drive budget It is ROHS3 compliant.","metaTitle":"STF28NM50N N-Channel MOSFET, 500V 21A TO-220FP, MDmesh II","metaDescription":"STF28NM50N N-channel 500V 21A MOSFET in TO-220FP full-pack.
