The IDH10SG60CXKSA2 is a 600 V, 10 A SiC Schottky diode from Infineon's CoolSiC™+ generation.
600 V / 10 A — where it fits the power stage
Rated for 600 V DC reverse and 10 A average forward current, this diode is sized for the boost diode in a 400 V bus PFC front-end or the freewheeling diode in a 3-phase motor drive up to a few kW. The 2.1 V forward drop at 10 A is typical for a SiC Schottky of this die size — conduction loss is higher than a comparable Si FRED, but the switching loss saving more than compensates above 50 kHz. That margin matters when the diode shares a heatsink with a hot MOSFET or IGBT in a compact enclosure.
Through-hole TO-220-2 — rework and heatsinking
The single-screw tab and wide lead spacing make it straightforward to hand-rework — a hot-air station or soldering iron can lift it without cooking adjacent components, and the tab is easy to clean and re-grease.
