Industrial-Grade CoolMOS S7 and the Automotive-Grade CoolMOS S7A MOSFETs for Industrial and Automotive Applications


Infineon Technologies has introduced the industrial-grade CoolMOS S7 10 mΩ and the automotive-grade CoolMOS S7A as an extension to its 600V CoolMOS S7 family. The product family has been developed by optimizing the renowned CoolMOS 7 technology platform. With a unique low on-resistance (R DS(on)) for 600 V super junction MOSFETs, the CoolMOS S7 10 mΩ is suitable for applications where minimal conduction losses are critical such as off-the-shelf solid-state relays (SSR).


The automotive-grade CoolMOS S7A has the ability to handle the system performance requirements set by solid-state circuit breakers (SSCB) and diode paralleling/replacement for high power/performance designs in automotive applications, such as the High Voltage (HV) efuse, HV disconnect battery disconnect switch, as well as on-board chargers.


With the lowest (R DS(on)) in the market, both the devices have been integrated into an innovative top-side cooled (TSC) QDPAK SMD package for offering excellent thermal behavior. These new devices can provide high power density and allow the designers to limit the size of heat sinks up to 80% and extend the current and voltage ratings without altering the form factor.


Features of 600V CoolMOS S7 MOSFETs

  • Best-in-class RDS(on) in SMD packages
  • Best super junction MOSFET RDS(on)
  • Optimized for conduction performance
  • Improved thermal resistance
  • High pulse current capability
  • Body diode robustness at AC line commutation
