The STF15NM60ND: Gate charge is 40 nC at 10 V, input capacitance 1250 pF at 50 V Vds. The TO-220 Full Pack (TO-220FP) isolates the back. Operating junction temperature spans -55 to 150 °C.
Obsolete — sourcing the STF15NM60ND today
ST lists the STF15NM60ND as obsolete. That means no factory orders, no last-time-buy window — the only channel is surplus and independent distribution. When a part hits this status, date-code provenance matters: stock that surfaces years after the official EOL needs verification, especially for a power device that may have sat in uncontrolled storage. We source against an RFQ, confirming availability and current pricing at quote time.
TO-220FP thermal reality
The full-pack variant changes how you handle heat. With no exposed drain tab, the 30 W dissipation ceiling is reached through the plastic body — a clip-on heatsink or forced air is typical. The package is electrically isolated, which simplifies mounting but limits thermal transfer compared to a standard TO-220 with a tab soldered to a copper plane. If your design assumed a tab-heatsink path, this part needs a different mechanical approach.
