Product details

650 V N-channel in an isolated TO-220FP

380 mOhm on-resistance and gate-drive budget

That is the conduction-loss anchor for the thermal design: at 6 A the dissipation is roughly 13.7 W, which the TO-220FP's 30 W power rating can handle with an adequate heatsink. Gate charge totals 33.3 nC at 10 V, so a standard gate-drive IC with a few hundred mA peak output can switch this part at moderate frequencies without excessive crossover loss.

Junction temperature range and application fit

Input capacitance is 983 pF at 50 V drain — low enough that the switching node ringing is manageable with a small gate resistor.

Frequently asked questions

Can STFU15NM65N replace STP15NM65N?

The STP15NM65N is a different ordering code within the same MDmesh™ II family. Pin compatibility and parametric overlap depend on the package variant — the STFU15NM65N uses the TO-220FP full-pack, while the STP15NM65N typically uses a standard TO-220 with exposed tab. Confirm the footprint and isolation requirements before substituting.

What is the equivalent of STFU15NM65N?

For a drop-in replacement, verify the package (TO-220FP), Vdss (650 V), Id (12 A), and Rds(on) (380 mOhm) against any candidate part.
