Product details

On-resistance is 950 mΩ maximum at 1.2 A with a 13 V gate drive, and gate charge is a light 10.5 nC at 10 V, which keeps switching losses manageable in moderate-frequency offline converters.

Infineon lists the IPA50R950CE as obsolete.

On-resistance is 950 mΩ at 1.2 A and 13 V drive. Input capacitance is 231 pF at 100 V drain.

Through-hole Full Pack — hand-solderable and heatsink-ready

The TO-220 Full Pack (PG-TO220-3-31) is the fully moulded, isolated package — no exposed metal tab, so you can bolt it to a chassis or heatsink without a thermal pad or mica washer. The mounting hole is standard for a TO-220. Maximum power dissipation is 25.7 W at case temperature, which is enough for a moderate-load flyback or PFC stage when the heatsink is sized properly.
