199 mOhm on-resistance — what it means for the power stage
The 199 mOhm Rds(on) at 10 V gate drive and 9.9 A drain current sets the conduction loss floor for the design. The 139 W package dissipation limit provides derating headroom for a properly heatsunk assembly.
Temperature range and package
Junction temperature spans -55°C to 150°C, covering military and industrial extremes without derating. The TO-220-3 (PG-TO220-3-1) footprint accepts standard heatsink clips and spring clamps; the exposed metal tab carries the drain potential, so insulating bushings or thermal pads are required for shared-heatsink layouts. Gate drive is specified at 10 V for the rated Rds(on); the ±20 V Vgs maximum allows headroom for ringing on long gate traces.
Sourcing and lifecycle
The IPP50R199CPXK carries an Active product status, meaning Infineon continues to manufacture the part with no announced end-of-life.
