Product details

900 mOhm Rds(on) and 12 nC gate charge — switching and conduction balance

The STW9N80K5: The 900 mOhm maximum on-resistance at 10 V gate drive and 3.5 A drain current is a moderate value for an 800 V MOSFET.

Active lifecycle and sourcing posture

The MDmesh K5 series is a current-generation offering from STMicroelectronics.

Frequently asked questions

What is the drain current rating of STW9N80K5?

The continuous drain current is 7 A at 25°C case temperature. Derate for higher ambient temperatures per the thermal curve in the datasheet.

Is STW9N80K5 RoHS compliant?

Yes, the STW9N80K5 is ROHS3 compliant.

Can STW9N80K5 replace FQA7N80C?

Both are 800 V, 7 A N-channel MOSFETs in TO-247-3 packages, so the basic ratings align. However, gate charge, on-resistance, and switching characteristics differ — verify the Rds(on) and Qg against your drive circuit and switching frequency before substituting.
