Product details

600 V, 10 A N-channel SuperMESH™ — the shelf-life view

The STP12NK60Z: Through-hole TO-220-3 package with the metal tab as the drain.

Obsolete — plan the BOM transition

That means STMicroelectronics has stopped production; no further factory orders can be placed. There is no official successor listed on this record, so a pin-compatible drop-in from the same family is not guaranteed — a design review is needed to qualify an alternate 600 V, 10 A N-channel MOSFET in TO-220.

The 600 V Vdss, 10 A continuous drain rating, and 640 mOhm Rds(on) at 10 V gate drive are the critical parametric anchors. The 59 nC gate charge is moderate.

Frequently asked questions

Is STP12NK60Z obsolete?

Yes, the STP12NK60Z is listed as Obsolete. STMicroelectronics has ended production.

What is the replacement for STP12NK60Z?

No official successor is recorded on this listing. A functionally equivalent replacement would be a 600 V, 10 A N-channel MOSFET in a TO-220 package with an Rds(on) at or below 640 mOhm at 10 V gate drive. The gate charge and capacitance should be verified against the existing drive circuit. A design review is recommended before substituting.
