Product details

600 V, 6 A, TO-220 Full Pack — what this MOSFET is

That means it is not formally discontinued, but the manufacturer advises against using it in new projects. Production may continue for existing designs, but the window for last-time-buy or final orders is narrowing. If you are starting a new design, look at the current SuperMESH portfolio for a pin-compatible replacement with similar voltage and current ratings.

Key ratings for the switching design

600 V Vdss suits offline flyback converters, PFC stages, and auxiliary power supplies. Gate charge is 46 nC at 10 V. Input capacitance is 905 pF at 25 V drain-source. Power dissipation ceiling is 30 W in the TO-220FP.

The TO-220 Full Pack package is through-hole, so it suits point-to-point wiring, perfboard prototypes, and production boards where a robust mechanical mount is preferred over surface-mount.

Frequently asked questions

Is STP6NK60ZFP obsolete?

Production may continue for existing BOMs, but the long-term supply window is narrowing.

What is the replacement for STP6NK60ZFP?

STMicroelectronics has not published a specific direct replacement for this exact NRND part. For a new design, evaluate current SuperMESH N-channel MOSFETs in the TO-220FP package with a 600 V Vdss and 6 A current rating. The STP6NK60 (non-ZFP variant) is the same die in a standard TO-220, but it lacks the full-pack isolation — check the package difference before substituting.

What is the difference between STP6NK60ZFP and STP6NK60?

Both share the same SuperMESH N-channel die with 600 V / 6 A ratings. The key difference is the package: STP6NK60ZFP is the TO-220 Full Pack (fully isolated plastic body), while STP6NK60 is a standard TO-220 with a metal tab that requires an insulating washer for heatsink mounting. The ZFP variant eliminates that washer and the associated assembly step.
