Isolated MOSFET Tube Driver Module - LR7843

  • Was  RM6.50 
  • RM5.50

  • Product Code: LR7843 MOSFET
  • Availability: In Stock




  • With optocoupler isolation, the control signal and the power of the controlled device are isolated, which greatly increases the rigidity of the interference.
  • Compatible with MCU and Arduino control board, 3V or 5V signal
  • High-level start, low-level stop, PWM speed regulation
  • Widely used to control the start and stop of the motor, solenoid valve and other tributary equipment
  • The signal input side can be welded to the terminal or pin itself, compatible breadboard
  • Output can be soldered to the terminal or direct wire



  • Input Voltage: 5V ~ 30VDC
  • MOS tube: LR7843, 30V 161A
  • Size: 23mm X 16mm


* PWM output to Arduino / any MCU pin, and connect GND to ground.
