Fairchild Semiconductor’s latest high-voltage field-stop shorted-anode trench IGBTs provide designers with a highly efficient, cost-effective solution to meet design challenges associated with high-power and high-frequency induction heating (IH) appliances that require lower conduction losses and superior switching performance in order to achieve higher efficiency and system reliability in applications such as IH rice cookers, table-top induction cookers and inverter-based microwave ovens.
Ranging from 1100-1400V, this new product family has been optimised with intrinsic anti-parallel diodes for soft switching applications. With advancements over the typical non-punch-through (NPT) IGBT technology, Fairchild’s shorted-anode silicon technology offers a lower saturation voltage of over 12 percent less than the same rating NPT-trench IGBT. Additionally, when compared to the competitor’s IGBT offerings, this product family offers a lower tail-current rate of over 20 percent. These rich features allow Fairchild’s advanced IGBTs to provide better thermal performance, higher efficiency and reduced power losses.
Features and benefits include: a high-speed switching frequency range: 10 to 50 kHz; a low tail-current for improved switching loss (FGA20S140P); low saturation voltage drop than existing NPT trench IGBTs; robust pot detection noise immunity for reliability; high temperature stable behaviour and RoHS compliant (Pb-free lead plating).
