Fairchild Semiconductor has introduced a 1200V/15A NPT-Trench IGBT with the ability to withstand as much as 300mJ of avalanche energy in induction heating (IH) applications. According to the company, this excellent avalanche capability helps ensure "rugged" fail-safe operation of the system during abnormal avalanche-mode conditions that commonly affect IH appliances such as microwave ovens, IH rice cookers and other IH cookers.

The FGA15N120ANTD promises optimum trade-offs between low conduction loss (VCE(sat), typ = 1.9V) and switching loss (Eoff, typ = 0.6mJ) to increase efficiency and significantly reduce the system's operating temperature.

"Fairchild's NPT-Trench IGBT achieves excellent system ruggedness in avalanche conditions, a primary concern for induction heating systems that must survive the typical onslaught of unstable power and AC line surges," said Taehoon Kim, vice president of the Functional Power Group. "With our customers in mind, we applied our proprietary technology to develop this new 1200V/15A NPT-Trench IGBT. The FGA15N120ANTD device's outstanding performance offers designers the high system efficiency and reliable operation necessary for IH appliances."

The new device is based on Fairchild's proprietary Trench cell design and thin wafer NPT process that enables the device to provide up to 300mJ of avalanche capability. When tested in a set evaluation using a 1.4kW/24kHz IH appliance, the trade-offs between the device's switching and conduction losses reduced operating temperature to 34.5C. In addition, this IGBT integrates a fast-recovery diode (FRD) to help designers reduce component count while further ensuring system reliability, the company said.

The FGA15N120ANTD is available in a Pb-free TO-3P package that complies with the requirements of the joint IPC/JEDEC standard J-STD-020C and the European Union requirements now in effect.

Available today, the device is priced at $3.30 each in quantities of 1,000. Delivery is 12 weeks ARO.
