Fairchild Offers Field Stop Trench 1200V IGBTs For Induction Heating Applications

Fairchild Semiconductor introduced a new series of 1200V Field Stop Trench IGBTs – the FGA20N120FTD and FGA15N120FTD – which are said to provide system designers of induction heating applications with a highly efficient solution. Using both Field Stop structure and avalanche-rugged Trench gate technology, these IGBTs are claimed to offer optimal tradeoffs between conduction losses and switching losses, which maximize efficiency.

According to the company, compared to conventional NPT-Trench IGBTs, the FGA20N120FTD offers 25% lower conduction losses and 8% lower switching losses, significantly reducing the system’s operating temperature. By lowering the cooling needs, it is claimed that system reliability is increased and overall system cost is reduced. It is stated that reliability is further ensured by a built-in fast-recovery diode (FRD) that is optimized for Zero Voltage Switching (ZVS) technology.

Fairchild’s FGA20N120FTD and FGA15N120FTD are said to minimize performance variability and device failures in avalanche-mode operation due to a tight parameter distribution and increased avalanche energy. This is achieved with Fairchild’s Field Stop structure and proprietary advanced Trench gate cell design.

Key features of the FGA20N120FTD and FGA15N120FTD are said to include: low switching losses to improve system efficiency; low saturation voltage to reduce conduction losses; built-in fast-recovery diode (FRD) optimized for ZVS topology to help designers reduce component count while further ensuring system reliability; tight parameter distribution to reduce performance variation; and excellent avalanche capability to extend operational life.

The FGA20N120FTD and FGA15N120FTD utilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.

The units are priced (each, 1000 pcs) as follows: FGA20N120FTDTU – US $4.00; FGA15N120FTDTU – US $2.80. They have a delivery time of 8 weeks ARO.
