N-Channel MOSFET, 66 A, 850 V, 3-Pin TO-264 IXYS IXFK66N85X

The 850V Ultra-Junction X-Class Power MOSFETs with fast body diodes represent a new power semiconductor product line from IXYS Corporation. These rugged devices 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, the new 850V devices exhibit the lowest on-state resistances (33 milliohm in the SOT-227 package and 41 milliohm in the PLUS264, for instance), along with low gate charges and superior dv/dt performance.
