Product details

Gate charge and capacitance — drive budget considerations

These figures are moderate for an 800 V MOSFET, meaning the gate-drive power requirement stays manageable — a standard 1 A gate-driver IC can switch it in the tens of nanoseconds.

Package and thermal — TO-262 full pack, 35 W dissipation

Housed in a TO-262-3 full pack (I2PAKFP, supplier device package I2PAKFP TO-281), this is a through-hole, isolated-tab package. Maximum power dissipation is 35 W at case temperature. The full-pack construction eliminates the need for an insulating pad between the tab and heatsink, simplifying assembly in high-voltage applications.

Frequently asked questions

What is the replacement for STFI13N80K5?

STMicroelectronics has not published an official successor order code for the STFI13N80K5 in the available records. For a pin-compatible replacement, evaluate other 800 V N-channel MOSFETs in the TO-262 full-pack package from the MDmesh K5 or later MDmesh series, such as the STFI13N80K5's siblings in the same package. Verify electrical compatibility (Vdss, Id, Rds(on), Qg) against your design margins before substitution.
