Hello Everyone,


I am trying to design DC solid state relay circuit using AUIRS21271STR gate driver and AUIRFR4620 mosfet to drive capacitive load such as motor controller. I have created the schematic for the circuit and would like to ask you to verify or suggest improvements on my design.

SSR design requirements:

  • maximum load current 10A
  • load voltage = upto 200V DC
  • load capacitance 200 uF
  • input isolation: required
  • signal voltage: 3.3V

Hi,

Since this is an automotive grade gate driver, kindly contact the local Infineon applications engineering team who can verify the design.

Thanks and regards,

Srivatsa
