== 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
