It comes in a through-hole TO-251 (IPAK) package — three short leads, no heatsink tab exposed, sized for compact PCB mounting where a TO-220 would crowd the layout. ## Mounting and thermal — TO-251 constraints The TO-251 (IPAK) package has a short lead form and a plastic body that sits flush against the PCB. No metal tab for external heatsinking — all 110 W maximum power dissipation (at Tc=25 °C) must be pulled through the copper pad and PCB plane. For continuous operation above a few amps, a dedicated drain copper area on the board is required; the datasheet's thermal impedance curve (junction-to-ambient) should guide the pad size. The through-hole leads suit wave-solder assembly but take up more board area than a DPAK — plan the keep-out zone accordingly. Derate the 11 A current rating above 100 °C case temperature per the datasheet curve. ROHS3 compliant.","metaTitle":"ST STU16N65M2 N-Channel MOSFET, 650V 11A TO-251","metaDescription":"STMicroelectronics STU16N65M2 MDmesh M2 N-Channel MOSFET, 650V Vdss, 11A Id, 360mOhm Rds(on) at 10V.
