Description
These series of T-modules use standard recovery
power rectifier diodes. The semiconductors are
electrically isolated from the metal base, allowing
common heatsink and compact assembly to be built.
Applications include power supplies, battery charges,
welders, motor controls and general industrial current
rectification.
