Product details

60 V / 45 A / 9.4 mOhm — the switching cell that sets the power budget

This is a through-hole part in the TO-262-3 package (PG-TO262-3-1), suited for high-current switching in power supplies, motor drives, and DC-DC converters where board space is less constrained and thermal management relies on a heatsink or chassis mount.

175°C junction — where the part lives when the ambient climbs

That extra headroom matters in engine-bay electronics, industrial ovens, or any enclosure where ambient air hits 85°C or more and the power dissipation pushes junction temperature.
