Toshiba’s new discrete IGBT for voltage resonance circuits contributes to lower power consumption and easier design of equipment.
Tokyo, December 2019 – 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 immediately.
GT20N135SRA features a collector-emitter saturation voltage of 1.75V and a diode forward voltage of 1.8V, approximately 10% and 21% lower, respectively, than for the current product. 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, 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 peak value is 129A, about a 31% reduction from the current product. As its safe operating area is widened, it makes equipment design easier compared to the current product.
Applications include home appliances (such as tabletop IH cookers, IH rice cookers and microwave ovens) that use voltage resonance circuits.
Toshiba works closely with customers to create electronic components and storage products that are designed to excite the marketplace and deliver on a shared vision of success. The company has spent decades developing strong relationships and applying resources to meet challenges.
