BUK9Y19-55B

N-channel TrenchMOS logic level FET

Logic level N-channel enhancement mode Field-Effect Transistor (FET) in a plastic package using TrenchMOS technology. This product has been designed and qualified to the appropriate AEC standard for use in automotive critical applications.

Features

  • Low conduction losses due to low on-state resistance
  • Q101 compliant
  • Suitable for logic level gate drive sources
  • Suitable for thermally demanding environments due to 175 °C rating

Target applications

  • 12 V and 24 V loads
  • Automotive systems
  • General purpose power switching
  • Motors, lamps and solenoids
