Making a 2 Volt 400 Amp bridge rectifier?
 

The 400CNQ center tap, high current, Schottky rectifier
module series has been optimized for very low forward
voltage drop, with moderate leakage. The proprietary barrier
technology allows for reliable operation up to 150 °C junction
temperature.

The cathode base is common.

How do you use 4 of these with respect to heat sink mounting and
electrical isolation?
