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. It comes in a through-hole TO-220-3 package (PG-TO220-3-1), the standard footprint for board-mounted power stages where a heatsink is expected. 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.

Temperature range and environment

The junction temperature range spans -55°C to 150°C.

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.
