Product details

The TO-220 Full Pack (TO-220FP) package gives a fully isolated tab — no mica insulator or thermal pad between the device and heatsink, which simplifies assembly and cuts the BOM by one part and one assembly step.

Conduction and switching — the numbers that size the heatsink and driver

At that operating point the conduction loss is roughly I²R = 9.1 W, which fits within the 25 W power dissipation limit but leaves margin for switching losses. Input capacitance Ciss is 538 pF at 100 V drain-source, confirming the light gate drive requirement.

Package and thermal — the TO-220FP advantage

The TO-220 Full Pack (TO-220FP) is a fully moulded through-hole package with the drain tab encapsulated in epoxy. No metal tab is exposed, so the device is electrically isolated from the heatsink without an insulating washer. For designs that already use a grounded heatsink, the isolated tab saves a washer and the assembly labour to fit it. Mounting is a single M3 screw through the tab hole into the heatsink; the package body is keyed to prevent rotation.

Frequently asked questions

What is the closest pin-compatible alternative to STF12N60M2 in this component family?

Within the MDmesh M2 family, the STF12N60M2 sits in the 600 V / 9 A / 450 mOhm tier. Higher-current siblings in the same TO-220FP package (e.g., the STF18N60M2 at 18 A) share the same footprint and pinout but carry a lower Rds(on) and higher gate charge — the trade-off is conduction loss versus switching loss. A direct parametric search on Rds(on) and Qg at the same voltage class will identify the closest match for a given loss budget.
