Ultra-Junction X-Class Power MOSFETs with fast body diodes are rugged devices that display the lowest on-state resistances in the industry, enabling very high power density in high-voltage power conversion applications. Developed using the charge compensation principle and proprietary process technology, these devices exhibit low gate charges and superior dv/dt performance. In addition, thanks to the fast soft-recovery body diode, these Ultra-Junction MOSFETs help reduce switching losses and electromagnetic interference (EMI).

Features:

Ultra low on-resistance R_DS(ON) and gate charge Q_g
Fast body diode
dv/dt ruggedness
Avalanche rated
Low package inductance
International standard packages

Advantages:

Higher efficiency
High power density
Easy to mount
Space savings

Applications:

Industrial switched-mode and resonant-mode power supplies
Electric vehicle battery chargers
AC and DC motor drives
DC-DC converters
Renewable-energy inverters
Power Factor Correction (PFC) circuits
Robotics and servo control
