IXYS Introduces Two New High Current 6kV Rectifier Diodes With Surge Current Rating of 36000 Amperes

LEIDEN, Netherlands & CHIPPENHAM, England — (BUSINESS WIRE) — October 6, 2015 — IXYS Corporation (NASDAQ: IXYS), an international power and IC semiconductor company, today announced that its wholly owned UK subsidiary, IXYS UK Westcode Ltd., introduced two new, 6kV pressure contact rectifier diodes. The two new diodes have current ratings of 2830A and 3090A and are encapsulated in fully hermetic ceramic packages with copper electrodes.

The new 69mm die devices are available in industry standard 26mm and 35mm thick packages. The 26mm parts have an average current rating of 3090A and the 35mm parts an average current rating of 2830A at a heat sink temperature of 55 degrees C. Both parts offer a surge current rating of 36kA. The fully hermetic package has a 66mm electrode contact diameter with an industry standard overall diameter of 100 mm. The construction uses a new improved process when compared to earlier IXYS high current rectifier diode designs with the silicon die directly bonded to a metallic disc. This improved structure offers both better transient thermal conditions and overall greater robustness, when compared to designs with free floating silicon. These new devices offer the possibility for reducing series parallel combinations in very high megawatt rectifier applications thereby reducing component count and simplifying the mechanical construction.

“These new devices offer the highest possible current density in this package size and are suited to applications in the high megawatts. Their introduction expands the range of parts offered by IXYS UK Westcode in this voltage class,” commented Frank Wakeman, IXYS UK’s Marketing and Technical Support Manager.

The new devices are available in industry standard 26mm and 35mm thick packages and three voltage grades. Designations are: 26mm thick package, W3090HA520 (Vrrm 5200V), W3090HA560 (Vrrm 5600V) and W3090HA600 (Vrrm 6000V) and 35mm thick package, W2830HE520 (Vrrm 5200V), W2830HE560 (Vrrm 5600V) and W2830HE6000 (Vrrm 6000V).

The 6kV voltage rating is ideal where 3kV DC output is required. Typical applications include traction rectifiers and substations, front end rectification for medium voltage drives and all rectifier applications requiring devices in this power rating.
