Product details

500 V, 15 A N-channel — what the TO-220FP body means on the board

The STF16NM50N is an N-channel MDmesh™ II MOSFET in a TO-220FP full-pack package, rated at 500 V drain-source and 15 A continuous drain.

Rds(on), gate charge, and the switching-loss trade-off

Maximum on-resistance is 260 mOhm at 7.5 A with 10 V gate drive.

Obsolete — sourcing reality and the search for a drop-in

STMicroelectronics lists the STF16NM50N as Obsolete. The STF16NM60N shares the same package and series but carries a 600 V rating — the higher Vdss may shift Rds(on) and gate charge, so check the parametric table before substituting.

Frequently asked questions

Where can I buy STF16NM50N?

The STF16NM50N is obsolete per STMicroelectronics.

What is the replacement for STF16NM50N?

No official replacement order code is recorded. The STF16NM60N is a 600 V variant in the same MDmesh II series and TO-220FP package, but its Rds(on) and gate charge differ — verify the parametric match against your operating point before substituting.
