For a production BOM that currently specifies this part, the window for last-time-buy orders has closed through official channels. Sourcing now runs through independent distribution, where remaining inventory is finite and date-code provenance becomes the critical check. ## 650 V, 11 A — the power-stage fit Its 650 V drain-to-source voltage rating and 11 A continuous drain current place it in offline flyback converters, auxiliary power supplies, and PFC stages where the bus voltage sits at 380 VDC or below with derating margin. The gate charge is 29 nC at 10 V, and the input capacitance measures 800 pF at 50 V Vds. The ±25 V maximum gate-to-source rating gives headroom for ringing on the gate node in a hard-switched topology. The 4 V gate threshold at 250 µA is typical for a standard-threshold MDmesh device — ensure the PWM controller's gate drive output swings to at least 10 V to achieve the specified Rds(on). This is a fully molded, isolated package — the metal tab is encased in epoxy, so the device can be mounted directly to a chassis or heatsink without an insulating pad. The through-hole leads suit wave-soldering or manual assembly.","metaTitle":"STF11NM65N N-Channel MOSFET, 650 V, 11 A, TO-220FP","metaDescription":"STF11NM65N MDmesh II N-channel MOSFET, 650 Vdss, 11 A Id, 455 mOhm Rds(on).
