IGBT packs oust thyristors at higher voltages

A new line of 1700V IGBT copacks and isolated package 1700V IGBT phase leg products incorporate Ixys' proprietary 1800V Sonic-FRD ultrasoft fast-recovery diodes.

Ixys Corp has released a new line of 1700V IGBT copacks and isolated package 1700V IGBT phase leg products with its proprietary 1800V Sonic-FRD ultrasoft fast-recovery diodes.

These new copack and phase leg products provide unique, cost effective options for customers with applications requiring 1700V power switching.

Ixys is offering its fast switching "A" version 1700V NPT IGBTs in copack and phase leg configurations for PWM applications with switching frequencies up to 50kHz.

These high voltage NPT IGBT discretes enable the elimination of more costly, lower performance solutions such as thyristors or series connected MOSFETs or IGBTs typically used at voltages above 1200V.

Offered as copacks, they offer a more complete solution for power conversion applications to improve efficiency and reliability due to reduced voltage drop, lower switching losses and the need for fewer components.

Enhancing the efficiency and noise performance of these copacks and phase legs is the use of Ixys 1800V Sonic-FRD ultrasoft, fast recovery diodes.

Ixys Sonic-FRD fast and ultrafast recovery diodes are designed for temperature stability with low forward voltage and ultralow, ultrasoft reverse recovery characteristics.

In addition, Ixys Sonic-FRD diodes are optimised to provide excellent dynamic avalanche ruggedness.

These diodes minimise losses in hard switching applications, while maintaining superior soft recovery characteristics to minimise switching noise and eliminate the need for costly snubber circuits.

Copacks will be offered in 16 and 32A versions with TO-247, TO-268, Plus247 and Isoplus247 package options.

A 24A rated phase leg configuration is offered in Ixys proprietary Isoplus i4-PAC.

The i4-PAC is a UL recognised isolated package incorporating a DCB ceramic isolator which provides 2500V RMS isolation with superior isolated thermal performance.

Two Isoplus i4-PAC versions are offered, including a solderable, leaded version and a surface-mountable version.

Ixys' new 1700V discrete IGBTs provide a lower cost solution using standard PCB assembly for a broad range of high voltage applications.

These high speed "A" copacks and phase legs are intended for high voltage, fast switching applications such as induction heating, induction cooking, 480 to 575V AC offline inverters, flyback power supplies, UPSs and microwave ovens.
