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. 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

The FGA15N120ANTD offers 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.”

Fairchild’s FGA15N120ANTD is based on the company’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 a low 34.5°C. In addition to these performance benefits, this compact IGBT integrates a fast-recovery diode (FRD) to help designers reduce component count while further ensuring system reliability.
