1350V IGBTs Optimized for Soft-Switching Applications

Alpha and Omega Semiconductor Limited (AOS) today announced the addition of AOK30B135W1 to its 1350V AlphaIGBT™ family. The new AOK30B135W1 has been optimized to deliver high performance by reducing switching loss in soft-switching home appliance applications such as induction cooking, rice cookers, and inverter-based microwave ovens.

The AOK30B135W1 is designed with the latest patent-pending AlphaIGBTâ„¢ technology platform and features industry-leading low VCE (SAT) and a quick turn-off to ease power loss throughout the conduction and switching process. The exceptional BVCES rating and durable BV performance allow for enhanced safety voltage margin to avoid substantial damage from voltage transients. Additionally, EMI is decreased as a result of soft turn-off current waveforms.

“The technology of induction heating provides precise cooking, a safer and cooler heating surface, and efficient heating of conductive materials,” said Dr. Brian Suh, Vice President of IGBT product line at AOS. “Highly efficient and rugged AOK30B135W1 enables robust and reliable operation of the heating system as well as an ideal combination of conduction and switching losses.”

Technical highlights include: 1350V IGBTs with freewheeling diode in a TO-247 package; High breakdown voltage offers ample design margin to improve system reliability; Lowest turn-off delay time, less than 200ns; IC (at 100 degrees C) = 30A; and TJ(max) = 175 degrees C.

The AOK30B135W1 is immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 10,000 pieces is $1.5.
