Schottky diode for MOSFET H-bridge
Electrical Engineering Asked by Ricardo Casimiro on February 14, 2021
how can I calculate the value of the schottky diode? I use 4 MOSFET N-channel IRF1404 instead of IRF510 in the schematic
The motor should withstand currents up to 100 A and 12v

There are no schottky diodes in your circuit: -
If however you meant the 4 diodes I've ringed in blue circles then there is no need for them because each N channel MOSFET has a bulk diode inside the chip that performs exactly the same function as those external 1N4001 devices (D1, D2, D3 and Another D3): -
