IXYS UK Westcode has upgraded the power density of its three 1.8kV pressure contact phase control thyristors and contained them in fully hermetic ceramic packages designed to have reduced thermal resistance. Suitable for soft starters, DC drives, and all controlled rectifiers, the new products include one 56mm die device with 50mm electrode contact diameter packaging and two 69mm die devices with 66mm electrode contact diameter packaging.

The new silicon dice designs are available in the same overall package footprint but offer more than 40 per cent higher current rating compared to existing designs. The 56mm die device has an average current rating of 2600A and its package has an industry standard overall diameter of 74mm. The 69mm die devices have average current ratings of 3175A to 3565A with industry standard overall diameter packaging of 101.5mm.

The 56mm die device is available in an industry standard 26mm thick package and two voltage grades. Designations are: N2600MC160 (Vdrm/Vrrm 1600V), N2600MC180 (Vdrm/Vrrm 1800). The 69mm die device is available in two industry standard package thicknesses, 26mm and 35mm, plus two voltage grades. Designations are: 26mm thick package N3565HA160 (Vdrm/Vrrm 1600V), N3565HA180 (Vdrm/Vrrm 1800) and 35mm thick package N3175HE160 (Vdrm/Vrrm 1600V), N3175HE180 (Vdrm/Vrrm 1800).
