500 V, 190 mOhm — the SMPS workhorse
The 47.2 nC typical gate charge at 10 V keeps switching losses manageable in hard-switched topologies up to the 100 kHz range. It is built for the primary-side switch in 500 V-class offline power supplies — flyback converters, PFC boost stages, and half-bridge resonant converters. The TO-220-3 through-hole package (PG-TO220-3) allows direct heatsink mounting with a screw or clip, and the 127 W power dissipation at case temperature gives realistic headroom for a thermally-constrained design. Operating junction temperature spans -55 to 150 °C, covering industrial and automotive under-hood environments without derating at the high end.
The 190 mOhm maximum on-resistance is specified at 6.2 A drain current with a 13 V gate drive. This Rds(on) value is the conduction-loss anchor for a 500 V part in this current class — a 6 A rms primary current at 90 % duty cycle dissipates about 6.8 W in conduction alone. Input capacitance Ciss is 1137 pF at 100 V drain-source — a moderate value that keeps the Miller plateau manageable and reduces cross-conduction risk during hard-switched transitions. The 13 V recommended drive voltage (max Rds(on) condition) aligns with standard 12 V or 15 V gate-drive rails used in offline power ICs.
Active production, ROHS3, through-hole package
It is ROHS3 compliant, free of the six restricted substances plus the four phthalates. The through-hole TO-220-3 package ships in tube form, standard for this form factor. No official successor or cross-reference is listed by Infineon. The surface-mount sibling in the same CoolMOS™ CE family — the IPD50R950CEAUMA1 — shares the same 500 V rating and gate-drive voltage but offers a higher 950 mOhm Rds(on) and lower 4.3 A current rating in a DPAK package.
