The STW75N60DM6: These numbers set the hard ceiling for the switching cell — the 600 V Vdss gives headroom on a 400 VDC bus (typical in PFC or flyback stages), while the 72 A Id rating is the conduction limit before the junction hits its thermal budget. The TO-247-3 through-hole package is the standard for this power class, letting you bolt the device to a heatsink through the mounting hole and keep the thermal path short.
