DESCRIPTION / APPLICATIONS
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.
