Stacks, Subsystems & Assemblies

Power semiconductor stacks and subsystems combine and coordinate solid state switches, diodes, thyristors, IGBTs, and transient voltage surge suppressors in compact, easy-to-install assemblies. The stacks most often serve as rectifiers and inverters. Each off-the-shelf stack made by Littelfuse includes a low-noise cooling fan and high-speed fuses to protect against short circuits. We also supply accessories for power semiconductor stacks and subsystems, including clips, clamps, mounting grease, and heat sinks. Contact us to discuss custom designing a stack if you do not find a prebuilt solution that meets your needs.
