Product details

600 V N-channel with an isolated tab — the TO-220FP thermal budget

The STF33N60M2: The 35 W power dissipation ceiling at case temperature is the practical limit in a real enclosure, not the 26 A continuous drain rating.

This is the figure a power supply engineer uses to size the heatsink for a given output power.

45.5 nC gate charge — driver current at the target switching frequency

For a 100 kHz hard-switching converter, the average gate-drive current is 4.55 mA, but the peak current required to charge the gate in the Miller plateau is higher — typically 1–2 A peak for fast turn-on.

Active production, isolated package — no LTB tracking, no insulating washer

It is ROHS3 compliant, covering the full restricted-substance list without exemptions. The TO-220 Full Pack package saves one assembly step (no insulating washer or thermal grease on the tab), but the thermal resistance is higher than the standard TO-220; the 35 W dissipation limit must be respected in the thermal design.

Frequently asked questions

Is STF33N60M2 RoHS compliant?

Yes, it is listed as ROHS3 compliant, covering the full restricted-substance list without exemptions.

Can I replace IRFP460 with STF33N60M2?

Both are 600 V N-channel MOSFETs in TO-220-type packages, but the STF33N60M2 is in the TO-220 Full Pack (isolated tab), while the IRFP460 is in a standard TO-247 or TO-220 with a non-isolated tab. The pinout differs — the IRFP460 has the drain connected to the tab, whereas the TO-220FP tab is isolated. The gate threshold and gate charge also differ. A direct drop-in replacement is not guaranteed without reviewing the pinout and the thermal mounting scheme in the existing design.
