Package and mounting
The IPN50R950CEATMA1: Gate charge is 10.5 nC at 10 V. Input capacitance is 231 pF at 100 V drain-source. Power dissipation is 5 W at the case.
Lifecycle and sourcing — active, no rush
Infineon lists the IPN50R950CEATMA1 as Active. No last-time-buy notice, no NRND flag. ROHS3 compliant. If you are stocking spares for a production line, this one is not going away soon.
Package and mounting — SOT223, no heatsink tab
The PG-SOT223 (TO-261-4) is a surface-mount package with a small drain tab on the top. For dissipation above 5 W, plan for copper-plane cooling on the PCB. Gate threshold is 3.5 V maximum at 100 µA drain current; 13 V drive gives minimum Rds(on).
