STW21N90K5 Frequently Asked Questions (FAQs)

  • The maximum operating frequency for the STW21N90K5 is 100 kHz, but it can be operated at higher frequencies with reduced performance.
  • To ensure proper thermal management, the STW21N90K5 should be mounted on a heat sink with a thermal resistance of less than 1°C/W, and the ambient temperature should be kept below 150°C.
  • The recommended gate drive voltage for the STW21N90K5 is between 10V and 15V, with a maximum voltage of 20V.
  • Yes, the STW21N90K5 can be used in a synchronous rectification application, but it requires a dedicated driver and a proper PCB layout to minimize parasitic inductance.
  • To protect the STW21N90K5 from overvoltage and overcurrent, a voltage clamp and a current sense resistor should be used, along with a protection circuit that can detect and respond to fault conditions.
