Frequently asked questions
Does the STW11NK90Z have a pin-compatible alternative?
The STW11NK90Z is the specific order code in the SuperMESH™ series for a 900 V, 9.2 A N-channel MOSFET in TO-247-3. No official pin-compatible second-source alternate is listed in the available records. For dual-sourcing evaluation, compare parts with the same voltage class, current rating, and TO-247-3 footprint.
