Working Method

Advantages of Mosfet

  • Optional use optical coupler, isolate signal, anti interferance.
  • High level signal turn ON, low to OFF, PWM to control speed

Common Used Applications

  • motor start and stop
  • solenoid valve
  • Bulb
  • LED Strip
  • Micro Water Pump
  • Solenoid Valve

Compare to Relay

  • High speed turn on and off
  • no noise, no spark, no interferance
  • longer life time

Parallel Connect MOSFET

  • Lower internal resistance
  • Higher passing current, higher driving power

Specifications

  • VGS(th) 1-2.5V
