Device offers design flexibility and reduced losses

Toshiba Electronics Europe has released a new discrete 1350V IGBT for employment in resonance-based home appliance applications that utilise induction heating, including tabletop cookers, rice cookers and microwave ovens.

The new GT20N135SRA IGBT offers a collector-emitter saturation voltage (VCE(sat)) of 1.60V (typ.), and a diode forward voltage (VF) of 1.75V, which realise reductions of around 10% and 21% respectively in comparison with conventional products as both the IGBT and diode have improved conduction loss characteristics at high temperature (TC=100C, the device will achieve more efficient operation.

Furthermore, an improved maximum junction-to-case thermal resistance (Rth(j-c)) of 0.48C/W provides for easier thermal design with less heatsinking as it signifies an approximate 26% reduction from current products.

The new device can suppress the short circuit current through a resonance capacitor that is produced when the device is started. The new product’s peak short circuit current is 129A, nearly a third lower than current products. The SOA is widened, indicating that the IGBT is less likely to break down, thereby providing designers with greater flexibility.

Housed in an industry-standard TO-247 package, the device can handle a maximum collector current (IC) of 40A, reducing with derating to 20A at 100C.
