DESCRIPTION
The series of T-modules uses fast recovery power diodes in
a single diode configuration. The semiconductors are
electrically isolated from the metal base, allowing common
heatsink and compact assemblies to be built.
These single diode modules can be used in conjunction with
the thyristor modules as a freewheel diode. Application
includes self-commutated inverters, DC choppers, motor
control, inductive heating and electronic welders. These
modules are intended for those applications where very fast
recovery characteristics are required and for general power
switching applications.
