High Power 32mm Die Phase Control Thyristors

IXYS Corporation announced two new 32mm die pressure contact phase control thyristors with  current ratings of 530A and 795A and voltage from 1400V to 2500V.

These new larger die size offer improved performance when compared to established part in the same overall mechanical footprint. The device includes a new  silicon die with advanced thermal bonding to a metal disc and encapsulated in a rugged hermetic ceramic packages The new improved package design includes fewer material interfaces and a much improved  gate contact, with reduced thermal resistance and enhanced electrical performance.

These new devices will eventually replace the older designs which will be phased out as customers take advantage of these new improved products.

The device is available in two current ratings and four different voltage grades. Designations are: N0795YN140 (Vdrm/Vrrm 1400 V and ITAV 795A), N0795YN180 (VDRM/VRRM 1800 V and ITAV 795A), N0530YN220 (VDRM/VRRM 2200 V and ITAV 530A) and N0530YN250 (VDRM/VRRM 2500 V and ITAV 530A).

Typical applications include soft starters, DC drives, and all controlled rectifier applications which require the higher reliability of a press-pack at these lower current ratings.
