For a new design, you would not qualify this part — the official ST successor (if one exists) is not recorded in the available lifecycle data, so the practical path is to find a functionally equivalent N-channel MOSFET in the same 650 V, 7 A class with a TO-220 package. ## Package and thermal — TO-220 through-hole Housed in a standard TO-220-3 through-hole package, the STP8N65M5 mounts into a PCB or heatsink with a single screw hole. The maximum power dissipation is 70 W at case temperature, so a heatsink is expected for any continuous load above a few amps. The junction temperature rating of 150°C sets the thermal derating limit — keep the case temperature below that margin when sizing the heatsink.","metaTitle":"STP8N65M5 N-Channel MOSFET, 650V, 7A, TO-220, Obsolete","metaDescription":"STP8N65M5 N-Channel MOSFET from STMicroelectronics MDmesh V series. 650V Vdss, 7A Id, 600mOhm Rds(on).
