650 V, 1 Ω — flyback primary and PFC boost stage fit
The 1 Ohm maximum on-resistance at 1.5 A, 10 V gate drive sets the conduction loss floor for a typical 65–100 W flyback converter primary switch or a continuous-conduction-mode PFC boost stage.
Input capacitance is 328 pF at 100 V drain-source, contributing to low capacitive switching losses in hard-switched topologies.
The through-hole leads suit single-sided boards or manual assembly runs where surface-mount reflow is not practical.
No official second-source or drop-in replacement is listed in the Infineon cross-reference; the closest functional peer is the IPD50R950CEAUMA1 (500 V, 950 mOhm, DPAK surface-mount), but the voltage class and package differ, so a board respin would be required.
