Product details

500 V CoolMOS in a TO-247 — what this part is for

The Infineon SPW12N50C3 is a 500 V N-channel CoolMOS power MOSFET in a TO-247-3 through-hole package. It is built for hard-switching topologies — power factor correction stages, flyback converters, and two-switch forward converters — where the 380 mOhm typical on-resistance at 10 V gate drive keeps conduction losses manageable at 11.6 A continuous drain current. The 49 nC gate charge at 10 V means a standard MOSFET gate driver can switch it without excessive drive power.

Temperature range and mounting

Rated for -55°C to 150°C junction temperature, this MOSFET can handle avionics, outdoor telecom cabinets, and engine-bay environments where the junction sees wide thermal swings. The TO-247-3 package (PG-TO247-3-21) bolts to a heatsink with a single M3 screw; the exposed metal tab is the drain.

Lifecycle and sourcing

Infineon lists it as current, with ROHS3 compliance. No last-time-buy notice or EOL warning has been issued.

Frequently asked questions

What is the Rds(on) of SPW12N50C3?

Maximum on-resistance is 380 mOhm at 7 A drain current with 10 V gate drive.

What are the differences between SPW12N50C3 and SPW11N50C3?

Both are 500 V CoolMOS N-channel MOSFETs in TO-247. The SPW12N50C3 has a lower Rds(on) (380 mOhm vs the SPW11N50C3's higher value) and a higher continuous drain current (11.6 A vs the SPW11N50C3's lower rating). The SPW11N50C3 is the lighter-duty sibling for designs where the extra headroom is not needed.
