Fairchild Semiconductor, a leading global supplier of high-performance power and mobile semiconductor solutions, is launching a new 1200V Field Stop Trench IGBT series. Used in hard-switching industrial applications such as solar inverters, UPS (Uninterruptible Power Supply), and welding machines, this new IGBT series provides power engineers with outstanding efficiency and reliability in their designs.

The newly released 1200V field stop IGBT series minimizes conduction losses with a VCE(SAT) of 1.8V, which is significantly lower than previous high-speed switching NPT IGBTs. The VCE(SAT) rating of this new device is the lowest among 1200V high-speed switching IGBTs currently on the market. Switching losses are also low, with an EOFF value of less than 30 μJ/A. All devices in this series include co-packed diodes optimized for high-speed switching.

Lee Myung-ho, Senior Vice President of Fairchild Semiconductor's 'Industrial Power Systems' team, stated, "New and innovative power electronics technologies are required to lower costs, improve efficiency, and enhance reliability for solar inverter manufacturers." “Fairchild’s 1200V Field Stop Trench IGBT Series helps customers achieve higher energy efficiency and reliability in solar inverter design, and helps manufacturers meet government regulations and the increased energy saving demands of end consumers,” he said.

With the new 1200V field stop trench IGBT series, designers can operate devices at higher switching frequencies compared to competing solutions, thereby reducing the size and cost of capacitors and inductive components required in the circuit. Ultimately, this enables system designs with higher power density and lower size and bill of materials (BOM) costs.

This IGBT series ensures a wider safe operating area (SOA) by undergoing 100 percent testing for clamped inductive switching at current levels up to four times the rated current.

Compared to previous generation products which were in TO264 packages, these products provide 15A, 25A, and 40A current ratings in a more compact TO247 package with a lead length of 20mm.

Key Features of the Product:
• Low saturation voltage: VCE(SAT) = 1.8V at rated collector current (Ic)
• High-speed switching: Low EOFF = 27μJ/A
• Wide SOA (100 percent inductive load switching test: ILM = 4 times Ic rating)
• Convenient parallel operation (positive temperature coefficient)
• Tj = 175°C (maximum junction temperature)
• High input impedance
• RoHS compliant

Fairchild Semiconductor's 1200V field-stop trench IGBTs provide industry-leading technology capable of addressing the energy efficiency and form factor challenges encountered in today's system designs. These applications are part of Fairchild's energy-efficient power analog ICs, power discrete devices, and optoelectronic solutions that maximize energy efficiency in high-power applications.
