Infineon expands superjunction MOSFET family
600V CoolMOS S7 family extension includes QDPAK top-side cooling packages
Infineon is expanding its 600V CoolMOS S7 family of high-voltage superjunction (SJ) MOSFETs. The new devices are suitable for SMPS, solar energy systems, battery protection, solid-state relays (SSR), motor-starters and solid-state circuit breakers, as well as PLCs, lighting control, HV eFuse/eDisconnect, (H)EV on-board chargers.
The portfolio extension includes QDPAK top-side cooling (TSC) packages to suit low-frequency switching applications while optimising cost, according to the company. The RDS(on) is 10 mΩ, which is believed to be the lowest on the market in this voltage class and the lowest in SMD packages.
Thanks to the QDPAK packaging, they also reduce or even eliminate the need for heat sinks in solid-state designs, resulting in more compact and lighter systems.
The MOSFETs are available in both top-side and bottom-side variants, and feature high-pulse current capability, enabling them to handle sudden surges of current. In addition, they exhibit body diode robustness to ensure reliable operation during AC line commutation.
The new 600 V industrial grade CoolMOS S7 and automotive grade CoolMOS S7A SJ MOSFETs for static switching are available in both top-side (TSC) and bottom-side cooling (BSC) QDPAK (PG-HDSOP-22) variants and can be ordered now.
