Product details

650 V N-channel in the MDmesh™ M2 family

The STMicroelectronics STFU18N65M2 is a 650 V, 12 A N-channel power MOSFET from the MDmesh™ M2 series, in a TO-220FP full-pack through-hole package. It targets hard-switched topologies in off-line power supplies, PFC stages, and lighting ballasts where the full-pack isolation simplifies heatsinking without a separate insulating pad.

Temperature range and package — deployment scope

The TO-220FP full-pack isolates the drain tab electrically from the heatsink, simplifying assembly in metal-enclosure designs.

Frequently asked questions

Is STFU18N65M2 RoHS compliant?

Yes, the STFU18N65M2 carries ROHS3 compliance certification, meaning it meets the EU RoHS directive with no exemptions for lead, mercury, cadmium, or other restricted substances.

Can STFU18N65M2 replace FQPF18N65V2?

The FQPF18N65V2 is a 650 V, 18 A N-channel MOSFET in a TO-220F package from ON Semiconductor. Both parts share the same package outline and voltage class, but the STFU18N65M2 is rated for 12 A continuous drain current versus 18 A, so a direct replacement depends on the actual load current in the design. Compare the Rds(on) and gate charge specs against your operating point before substituting.
