Toshibas New Discrete IGBT for Voltage Resonance Circuits Contributes to Lower Power Consumption and Easier Design of Equipment

2019-12-23 | Return

TOKYO— Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched the  “GT20N135SRA,” a 1350V discrete IGBT for use in voltage resonance circuits in tabletop IH cookers, IH rice cookers, microwave ovens and other home appliances. Shipments start today.

GT20N135SRA features a collector-emitter saturation voltage[1] of 1.75V and a diode forward voltage[2] of 1.8V, approximately 10% and 21% lower, respectively, than for the current product[3]. Both the IGBT and diode have improved conduction loss characteristics at high temperature (TC=100℃), and the new IGBT can help reduce equipment power consumption. It also features a junction-to-case thermal resistance of 0.48℃/W (max), about 26% lower than that of the current product[3], allowing easier thermal design.

The new IGBT suppresses short circuit current that flows through the resonance capacitor when equipment is switched on. Its circuit current[4] peak value is 129A, about a 31% reduction from the current product[3]. As its safe operating area is widened, it makes equipment design easier compared to the current product[3].

Applications
>>Home appliances (such as tabletop IH cookers, IH rice cookers and microwave ovens) that use voltage resonance circuits

Features
>>Low conduction loss:
VCE(sat)=1.6V(typ.) (@IC=20A, VGE=15V, Ta=25℃)
VF=1.75V (typ.) (@IF=20A, VGE=0V, Ta=25℃)
>>Low junction-to-case thermal resistance: Rth(j-C)=0.48℃/W (max)
>>Suppresses short circuit current that flows through the resonance capacitor when equipment is switched on.
>>Wide safe operating area
