Infineon 600V CoolMOS™C6 Power MOSFET



CoolMOS™C6 is Infineon's fifth generation of high voltage power MOSFETs designed according to the revolutionary superjunction (SJ) principle. The new CoolMOSC6 series combines our experience as the leading SJ MOSFET supplier with best-in-class innovation. The resulting C6 devices provide all benefits of a fast switching SJ MOSFET while not sacrificing ease of use. C6 to achieves extremely low conduction and switching losses and can make switching applications more efficient, more compact, lighter and cooler. Moreover, it has the best cost/performance ratio on the market today.
Product Features:
  • Low area specific on-state resistance(Ron* A)
  • Low energy storage in output capacitance (Eoss)
  • High body diode ruggedness
  • Low reverse recovery charge (Qrr)
Benefits:
  • Easy control of switching behavior
  • Better light load efficiency compared to C3
  • Proven CoolMOSTM quality combined with high body diode ruggedness guarantee outstanding reliability
  • Lower price compared to previous CoolMOSTM generations
Applications:
  • PFC stages for server, PC silverbox, LCD & PDP TV, lighting, adapter





power MOSFET definition - computer

A type of metal oxide semiconductor field effect transistor (MOSFET) used to switch large amounts of current. Power MOSFETs use a vertical structure with source and drain terminals at opposite sides of the chip. The vertical orientation eliminates crowding at the gate and offers larger channel widths. In addition, thousands of these transistor "cells" are combined into one in order to handle the high currents and voltage required of such devices.


Following are the common types of power MOSFETs. The last example is a combination MOSFET and bipolar junction transistor (BJT), known as an "insulated gate bipolar transistor" (see IGBT). See MOSFET.

Power MOSFETs

All power MOSFETs use a vertical structure in which the source and drain are at opposite sides of the chip. The last example is a combination of MOSFET and bipolar technologies, which is typically used in higher power applications.
