Discrete IGBTs optimises low switching and conduction losses

Discrete IGBTs for resonant technologies, using bi-directional current flow have been announced by Infineon Technologies. It offers the RC-E devices for induction cooking appliances.

The RC-E family has an IGBT with monolithically integrated reverse conduction diode for resonant switching. Switching frequency is 8.0 to 40kHz.

According to the company, lower losses allow designers to achieve efficiency and power targets for induction cooking applications, as less energy is consumed for cooking. Low E off, V F, R th and V ce(sat) are claimed to set a new industry benchmark in price/performance and ease-of-use.

Fulfilling all the requirements for soft switching applications and efficiency as well as EMI standards, the RC-E delivers the performance of its predecessors with a more attractive price for lower BoM cost. It is offered in a standard TO-247 package, allowing a drop-in replacement for existing designs.

Samples are available now and the devices are in production. Two devices are available, 15 and 25A versions. Both with the most commonly used blocking voltage of 1,200V.
