IXYS UK Westcode Introduces a New High Power Fast 3.2kV Thyristor with Record Power Density and Efficiency for High Power Swi...
February 16 2017 - 8:30AM
IXYS Corporation (NASDAQ:IXYS) an international power and IC
semiconductor company, today announced that its wholly owned UK
subsidiary, IXYS UK Westcode Ltd., launched a new higher voltage
class fast distributed gate thyristor. This new fast thyristor with
turn-off time of as little as 65 microseconds and current rating of
1055 amperes, with forward and reverse blocking voltage rating of
3.2kV has unmatched performance for both voltage and current fed
applications providing megawatts of power control capabilities.
The device offers a higher voltage rating, while
retaining a fast turn-off time, when compared to other parts in
this package size. It expands the performance envelope in high
power control systems. This new improved design has an average
current rating of 1055 amperes at a heat sink temperature of 55
degrees Celsius. The improvement in performance is achieved by
optimising the vertical structure in the device, to give increased
voltage without compromising the reverse recovery characteristics
of the device. The die size has been maximised with improved
distributed gate geometry, optimised for the design turn-off speed
and operating frequency. The 53 mm silicon die is bonded to a metal
disc to give optimum thermal performance and encapsulated in fully
hermetic 47 mm electrode contact diameter ceramic packages, with an
industry standard overall diameter of 74 mm. Provided the
correct thermal conditions are observed, with a repetitive di/dt
rating of 300 amperes per microsecond, the device can be used in
applications with repetitive frequency up to 5 kilohertz.
“With a higher voltage grade than other parts
offered with this switching speed, the new device presents the
option to replace two lower voltage devices operated in series to
achieve a desired switching speed and operating voltage; thus
simplifying mechanical design and reducing the number of system
parts,” commented Frank Wakeman, IXYS UK’s Marketing and Technical
Support Manager.
The full symmetrical blocking device is
available in two different switching classes at two standard
voltage grades, part number designations are as follows: 3600 volt
parts are R1045NC36L with turn-off time 65 microseconds and
R1045NC36M with turn-off time 70 microseconds; 3200 volts parts are
R1045NC32L with turn-off time 65 microseconds and R1045NC32M with
turn-off time 70 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.
