Product details

STMicroelectronics lists the STP25NM60N as Obsolete. Stock that surfaces should be date-code checked and preferably from a known production date window; mystery lots with no provenance carry a higher counterfeit risk on an obsolete device.

Key ratings for the switching design

The 600 V Vdss gives a comfortable derating margin for universal-input (85–265 VAC) PFC stages where the bulk rail sits around 400 VDC. Input capacitance is 2400 pF at 50 V drain bias, which is moderate for this voltage class.

Frequently asked questions

What is the replacement for STP25NM60N?

No official replacement order code is listed by STMicroelectronics. A functional replacement requires a 600 V N-channel MOSFET in TO-220 with similar Rds(on) and gate charge. The STP25NM60N uses MDmesh II super-junction technology, so a modern MDmesh V or MDmesh K5 part from ST, or an equivalent from Infineon's CoolMOS series, would be the starting point for a parametric cross — but each candidate must be validated for gate-drive voltage, switching speed, and thermal performance in the specific application.
