    Hi there,,

    Is there any chip or module that contines diodes with power MOSFET (four diodes and one MOSFET). I need it for positive and negative current direction control. The configuration is as described below (A) for anode (B) for cathode


    (A)diode1(C) (C) diode2 (A)

    Power MOSFET

    (C)diode3(A) (A) diode4 (C)

    Thanks in advance

    A circuit would help to understand what you plan to do. Have you taken into account that mosfets conduct both directions when turned on?

    Are you making a rectifier bridge or simply need reverse polarity protection?

    For reverse polarity, you just need a P-Type MOSFET with a low RDS like the SUD19P06-60L

    There are bridge rectifiers readily available.
