IXYS Expands its High Efficiency and High Power Rectifiers for Rail, Traction and Marine Drive Applications

BIEL, Switzerland--(Business Wire)--
IXYS Corporation (NASDAQ:IXYS) announced that its wholly owned UK subsidiary,
Westcode Semiconductors Limited, expanded the 50mm pole rectifier product range
with improved power density and efficiency. The introduction of four new devices
expands the voltage range to include products from 300V to 6kV. These new
additions offer maximum performance within the confines of an industry standard
footprint thereby minimizing size and weight while maximizing power.

The average current rating represents a 50% increase over present products of
the same voltage and overall package size. Improved performance is achieved by
maximizing the active silicon area and an improved vertical structure. The pole
rectifier design allows for double sided cooling thus offering best in class
thermal and electrical efficiencies. In addition to the increased average
current rating, the device also offers enhanced surge ratings and can be
supplied to special order in an extended case rupture current housing for
advanced system safety. The new introductions are available in four voltage
classes; 300V to 600V, 1.2kV to 1.5kV, 1.8kV to 2.2kV and 5.2kV - complementing
the five devices already introduced:

Part Number VRRM (V) IFAV TK = 55 degrees C
New W2115MC520-600 5200 to 6000V 2115A
W2899MC320-480 3200 to 4800V 2899A
W3082MC420-450 4200 to 4500V 3082A
W3477MC360-400 3600 to 4000V 3477A
W3708MC320-350 3200 to 3500V 3708A
W3842MC160-280 1600 to 2800V 3842A
New W4767MC180-220 1800 to 2200V 4767A
New W5636MC120-150 1200 to 1500V 5636A
New W7045MC030-060 300 to 600V 7045A

Frank Wakeman, Westcode`s Marketing & Technical Support Manager, commented,
"Increasing the ratio of power per weight of these rectifier diodes facilitates
the design of smaller and lighter power systems in mobile applications such as
the front-end rectifiers in Traction main drives, plus Marine and off-shore
applications. Additionally the devices are suitable for all front-end and
general rectification applications, such as track-side substations and power
conversion, offering a highly competitive cost per ampere ratio."
