600V CoolMOS N-channel — switching power supply workhorse
The through-hole TO-262 (I²Pak) package with long leads allows the backside tab to be bolted to a heatsink, pulling heat into the chassis rather than the board.
The 54 nC total gate charge at 10 V is moderate for a 600 V, 11 A device — a gate driver with 1 A peak source/sink capability can switch it in the 50–100 ns range, keeping crossover losses manageable at 50–100 kHz. Input capacitance Ciss is 1460 pF at 25 V drain-source, which sets the gate-drive impedance required to avoid Miller-plateau ringing. The 125 W power dissipation ceiling in the TO-262 package means the thermal interface to the heatsink is the real limit on continuous output current, not the die itself.
For a production BOM, this means no near-term requalification risk.
Temperature range and thermal design boundary
The 125 W power dissipation figure at Tc=25°C is the theoretical maximum with an infinite heatsink; real-world designs derate based on the thermal resistance of the TO-262 tab-to-heatsink interface and the ambient air temperature inside the enclosure.
