Product details

600 V N-channel in a fully isolated TO-220

The STF12NK60Z is supplied in the TO-220 Full Pack (TO-220FP) — a fully moulded through-hole package with no exposed metal tab.

Input capacitance is 1740 pF at 25 V drain-source.

Thermal and mounting reality

Maximum power dissipation is 35 W at case temperature, and the maximum junction temperature is 150 °C. The through-hole leads need a hole pattern on the PCB; no special footprint beyond the standard TO-220 three-hole layout.

It is ROHS3 compliant.

Frequently asked questions

What is the Rds(on) of the STF12NK60Z?

Maximum on-resistance is 640 mOhm at 5 A drain current and 10 V gate drive. This is the value at 25 °C junction — expect Rds(on) to increase with temperature per the normalised curve in the datasheet.

Can the STF12NK60Z replace the STP12NK60Z?

The STF12NK60Z is the fully isolated TO-220FP version of the same die. The STP12NK60Z uses a standard TO-220 with an exposed metal tab. Electrically the ratings are the same, but the package difference changes the thermal path and mounting — the STF variant bolts directly without an insulator, while the STP needs one if the heatsink is grounded.
