The new ComPack family represents a compact package with the highest power density. The ComPack design is a result from the
implementation of the newest assembly methods in combination with the proprietary ‘power metallization chip’ technologies of IXYS.
Advancement in the module design as well
as the silicon die technology leads to a userfriendly product that fulfills the highest needs
in reliability and
functionality.

“The ComPack module is an excellent example of how innovations in design can provide
benefits to our customers. Previous designs
of a phase leg bi-polar module and similar
competitive offerings are only rated between
500A and 570A. However, the ComPack is
rated at 700A and up to 2,200V per die but

With this development, IXYS is allowing the
designer to switch more power than historically available, thereby facilitating higher power densities, greater material efficiency and
lower systems cost and lower weight in motor
control, soft starter, UPS or input rectification
applications.

Anode Gated Thyristor (AGT) Technology Platform
The first product derived from this new technology platform is the CLB30I1200HB, a 30A /
1200V Single Thyristor in a TO-247 discrete package. The gate control of the CLB30I1200HB
is connected to the Anode side of the silicon die
instead of to the Cathode side, as done by a
standard Thyristor.
The combination of the Anode Gated Thyristor together with a standard Thyristor, e.g. the
CLA30E1200HB, gives several interesting configurations. Thyristor Phase-leg configurations
normally contain two separated gate driver
potentials but, by replacing one Thyristor with
the AGT, it will reduce to only one gate driver
potential. This will save one complete gate driver circuit. Also an AC switch configuration be-

nefits from the AGT, also here the switch can be
operated with only one gate drive circuit. This
shows great cost saving possibilities by reducing the gate drive component count. Therefore
it will also have a positive impact on the Mean
Time To Failure (MTTF) in the final application.

Several applications are targeted by the Anode Gated Thyristor for example line rectifying,
doft-starters, DC motor control, AC power /
lighting and temperature control. Generally
in all applications that use thyristors and / or
TRIAC’s the Anode Gate Thyristor will benefit.
