Fairchild intros shorted-anode IGBTs

USA: High-power and high-frequency induction heating (IH) appliances 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.

Fairchild Semiconductor’s high-voltage field-stop shorted-anode trench IGBTs provide designers with a highly efficient, cost-effective solution to these design challenges.

Ranging from 1100-1400V, this new product family is optimized 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:
• High-speed switching frequency range: 10 to 50 kHz.
• Lowest tail-current in industry for improved switching loss (FGA20S140P).
• Low saturation voltage drop than existing NPT trench IGBTs.
• Robust pot detection noise immunity for reliability.
• High temperature stable behavior: Tj(max) = 175 degree C.
• RoHS compliant (Pb-free lead plating).
