IXYS Introduces New 2.8kV, 3115A Fast Thyristor with Improved Power Rating
12 Septembre 2017 - 2:30PM
IXYS Corporation (NASDAQ:IXYS), an international power and IC
semiconductor company, today announced the launch of a new
distributed gate thyristor with increased power density. This new
fast thyristor with turn-off time of as little as 50 microseconds
has an average current rating of 3115 amperes. The device is
symmetrical blocking with up to 2800 volts and is therefore
suitable for both voltage and current-fed applications.
The 83mm diameter silicon dice are bonded using
a new improved process to ensure the best steady state and thermal
transient performance which replaces older design devices based on
floating silicon. The improved mechanical design of the package
offers maximum power performance and minimises material to give
exceptional reliability in the harsh operating conditions
experienced in resonant power supplies for induction heating
applications. With an average current rating of 3115 amperes at a
heatsink temperature of 55 degrees Celsius, the new device has
higher rating than present floating silicon design device it
replaces, while retaining the same mechanical footprint. The new
fast thyristors have an improved pilot thyristor design. The
redesigned distributed gate geometry for the main thyristor gives
improved gate trigger characteristics and transfer of current from
the pilot device while retaining the requirement for a high rate of
change in current capability.
“Provided the correct thermal conditions are
observed, with a repetitive rate of change of current of 1000
amperes per microsecond, the device can be used in applications
with repetitive frequency up to 5 kilohertz, a condition previously
not achievable with a device of this voltage and current rating,”
commented Frank Wakeman, IXYS UK’s Marketing & Technical
Support Manager.
The dice are encapsulated in a 26mm thick, fully
hermetic 75mm electrode contact diameter ceramic packages, with an
industry standard overall diameter of 112mm.
The fully symmetrical blocking device is
available in two different switching classes at two standard
voltage grades, part number designations are: 2.4KV parts are
R3115TJ24J with turn-off time 50 microseconds, and R3115TJ24K with
turn-off time 60 microseconds; 2.8KV parts are R3115TJ28J with
turn-off time 50 microseconds, and R3115TJ28K with turn-off time 60
microseconds.
Typical applications for this device include:
induction power supplies for melting, billet heating and surface
treatments, as well as resonant power supplies and pulse switches
for applications including high power magnets and lasers.
