Product details

Full-pack TO-220FP — isolated tab, no washer needed

The TO-220FP full-pack package (supplier device code TO-220FP) has an isolated back tab, so the heatsink interface does not require an insulating pad or mica washer. This simplifies mechanical assembly and reduces thermal resistance between the junction and the heatsink, but the package limits maximum power dissipation to 30 W at case temperature — about half what a standard TO-220 with a conductive tab can handle.

STMicroelectronics lists the STF30N65M5 as Obsolete. For new designs, a pin-compatible alternative from the same MDmesh V family should be evaluated — the 650 V, 22 A, TO-220FP footprint is common across several ST part numbers.

Frequently asked questions

What is the replacement for STF30N65M5?

No official replacement part number has been published by STMicroelectronics. A functionally similar N-channel MOSFET in the same MDmesh V family with 650 V drain rating, 22 A current capability, and TO-220FP package should be evaluated as a drop-in candidate. The base product number STF30N indicates the 30 A class in the full-pack family.
