Alpha and Omega Semiconductor Ltd. (AOS) recently introduced the new E-series IGBT platform with the 1200V AOK20B120E1 and 1350V AOK20B135E1. This new platform delivers low switching losses in soft-switching home appliance applications such as induction cooking, rice cookers and inverter-based microwave ovens.

The devices for the E-Series are built upon AOS's patent-pending AlphaIGBT™ technology platform, and feature VCE (SAT) and fast turn-off characteristics that reduce the power losses incurred during conduction and switching. The high BVCES rating and rugged BV performance provide a larger resonant voltage safety margin to prevent avalanche destruction from voltage transients. Moreover, EMI is minimized as a result of smooth turn-off current waveforms.

Technical Highlights

• 1200V/1350V IGBTs with freewheeling diode in a TO-247 package
• Low turn-off delay time: less than 200ns
• EOFF increase by the temperature (25°C vs. 150°C): less than 50%
• IC (100°C) = 20A
• TJ(max) = 175°C
• VCE(SAT) = 1.68V typ (AOK20B120E1)
• VCE(SAT) = 1.8V typ (AOK20B135E1)

The AOK20B120E1 and AOK20B135E1 are immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 10,000 pieces of AOK20B120E1 and AOK20B135E1 is $1.82 and $1.72, respectively.
