How To Use M7

The M7 is a high voltage rectifier diode with a high continuous current capacity of 1A. It can be used in rectifier and reverse voltage protection applications in electronic appliances like chargers. Although the stated continuous current is 1A, the diode can handle more current if the duration of the pulse is short enough, up to 30A if a single half-sine wave at 60Hz is passed through it.



  • Full bridge rectifier
  • Reverse voltage protection
  • Overvoltage clamping
