IXYS UK Introduces a Range of New Very High Current Fast Recovery Diodes for High Megawatt Applications
October 10 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 range of 4500
volt very high current fast recovery diodes (HP-sonic FRDs) with
nominal operating currents from 1800 to 3000 amperes, to be used in
conjunction with IXYS’ family of very high current press-pack
IGBTs.
The new diodes incorporate IXYS UK’s most
advanced die bonding technology, where the silicon die is bonded to
a metallic disc, replacing older designs based on floating silicon.
The new bonded die design offers a diode with improved thermal
stability and very robust mechanical properties. The silicon is
optimised with advanced processing to give an unrivalled rate of
change of current capability to more than 5000 amperes per
microsecond, while retaining a soft recovery characteristic and low
switching losses.
The diodes are packaged in fully hermetic 26mm
thick ceramic packages with copper electrodes, and are compatible
for series clamping in the same stack as IXYS UKs range of very
high current press-pack IGBTs. The 3000 ampere device has a 96mm
die and the 2400 ampere device has a 91mm die. Both are packaged in
an 85mm electrode package with an overall diameter of 125mm. The
1800 ampere device has an 83mm die and is packaged in a 75mm
electrode package with an overall diameter of 112mm.
Parts number designations are as follows: 3000
ampere device, E3000EC45E, 2400 ampere device, E2400EC45E and 1800
ampere device, E1800TC45E. The two lower current devices will
replace the older C series floating silicon products and the 3000
ampere device extends the range to cover the new 3000 ampere
press-pack IGBT.
“These new diodes combine IXYS’s established and
market leading HP-sonic FRD fast diode technology with our best
practice silicon bonding technology. These advanced diodes will
replace our older floating silicon devices and will offer the
customer the ultimate in reliability,” commented Frank Wakeman,
IXYS UK’s Marketing and Technical Support Manager.
The new HP sonic FRDs are optimised for use with
IXYS UK’s range of 4500 volt press pack IGBTs as both anti-parallel
and neutral point clamp diodes for multi-level converters. Typical
applications for this device include: utilities and HVDC
applications such as, flexible AC transition systems, HVDC
transition, Statcoms, VSC SVC etc.; medium voltage AC drives for
harsh environments and ultra-high power, such as mining, marine and
off shore, gas and oil installations; and renewable energy for wind
turbines, hydro generation, wave-generation and solar. As well as
applications incorporating IXYS UKs press-pack IGBTs, the devices
are also suitable for use with other very high power switching
devices which require the same combination for very high di/dt and
soft recovery, such as IGCTs (integrated gate-commutated
thyristor).
