Product details

800 V, 11 A — the switching envelope for this CoolMOS N-channel

Conduction and switching — what the parametric ratings drive

The 450 mOhm Rds(on) at 10 V gate drive sets the I²R conduction loss at 11 A to about 54 W — the 34 W maximum power dissipation at the case (Tc) means the device must be heatsunk to stay within the SOA at full current. Input capacitance is 1600 pF at 100 V drain-source — this sets the switching energy stored in the Miller plateau and influences the turn-on delay.

Package and thermal — through-hole with an isolated tab

Through-hole mounting suits point-of-load and bulk-power stages where the PCB is not the primary thermal path.

The wide temperature envelope also covers outdoor telecom and factory-floor equipment.

Frequently asked questions

What is the closest functional alternative to SPA11N80C3XKSA2?

The IPD50R950CEAUMA1 is a CoolMOS CE N-channel MOSFET, but it is a 500 V device rated for 4.3 A continuous drain with a 950 mOhm on-resistance — a significantly lower current and voltage rating than the 800 V, 11 A SPA11N80C3XKSA2. These are not drop-in replacements; the SPA11N80C3XKSA2 targets higher-power stages where the voltage and current headroom are needed.

Is SPA11N80C3XKSA2 RoHS compliant?

Yes, the SPA11N80C3XKSA2 is ROHS3 compliant, meeting the current EU restriction on hazardous substances.
