The newly released HV SJ power MOSFET series, CoolMOS™ CFD7A, merges unrivaled technology know-how with the proven Infineon automotive quality standards - going beyond AEC-Q101. The intrinsic fast body diode and the higher efficiency levels make it a sound device for PFC / DC-DC stages. Typical battery system voltages up to 475 V can be reached and the reduced switching losses result in excellent light- / full-load efficiency. On-board charger designs will become more compact and high-performing.
