Product details

600 V CoolMOS — the isolated-tab workhorse for offline power stages

The SPA03N60C3XK: The full-pack moulding means the metal tab is fully encapsulated, so the mounting hole is electrically isolated; you bolt it directly to the chassis or heatsink and skip the sil-pad.

Gate charge is 17 nC at 10 V. Input capacitance is 400 pF at 25 V drain-source.

TO-220 Full Pack — footprint and thermal reality

The PG-TO220-3-111 has the same mounting hole pattern as a standard TO-220. Maximum power dissipation is 29.7 W at case temperature.

For dual-sourcing or a pin-compatible second source within the same family, the standard TO-220 (non-isolated) sibling shares the same die but requires an insulating pad — verify the package variant before substituting.

Frequently asked questions

What is the closest pin-compatible alternative to SPA03N60C3XK?

Within the CoolMOS C3 family, the standard TO-220 (non-isolated) variant with the same 600 V / 3.2 A rating is pin-compatible but has a metal tab that requires an insulating pad for heatsinking. The SPA03N60C3XK's Full Pack package eliminates that pad.
