Power Modules

Diode modules and thyristor modules for power control applications perform best when they possess low thermal impedance and high overload capacity. Each of the modules produced by Littelfuse meet those requirements while also exhibiting low current leakage and low forward voltage drop. Designed for easy bolt-down mounting, our diode and thyristor modules offer full pressure contact to ensure high efficiency. Manufactures typically install the modules as rectifiers, ac–dc converters, and ac switches in induction heaters, electric motors, and lighting controls.
