Product details

500 V CoolMOS in a TO-220 — what this part is for

The Infineon SPP12N50C3 is an N-channel power MOSFET from the CoolMOS™ series, rated for 500 V drain-source voltage and 11.6 A continuous drain current at 25°C case temperature. Typical applications include hard-switching and resonant topologies in offline switch-mode power supplies, power-factor correction (PFC) stages, and industrial power converters where 500 V blocking voltage and moderate conduction loss are the primary requirements.

380 mOhm Rds(on) and 49 nC gate charge — the switching trade-off

The on-resistance of 380 mOhm at 7 A and 10 V gate drive defines the conduction loss for a given load current.

Frequently asked questions

Is SPP12N50C3 RoHS compliant?

Yes, the SPP12N50C3 is ROHS3 compliant.

What is the closest functional alternative to SPP12N50C3?

Within the CoolMOS family, the IPD50R950CEAUMA1 is a 500 V N-channel MOSFET from the CoolMOS CE series, but it is a lower-current 4.3 A device in a surface-mount DPAK package — not a direct pin-compatible replacement for the TO-220 SPP12N50C3. For a through-hole alternative, look at other CoolMOS C3 parts in TO-220 with similar Vdss and current ratings.
