STMicroelectronics' STGWA40IH65DF and STGWA50IH65DF 650V STPOWER™IGBT provide optimal on-off and on-off performance in soft switching circuits, improving the energy efficiency of resonant converters in the 16 Khz-60 KHZ switching frequency range.
The new IH series is part of STMicroelectronics' gate-gate Field Cutoff (TFS) IGBT family optimized for soft switching applications. It is suitable for half bridge circuits in appliances such as induction cookers and soft switching applications. Product designers can now choose these IGBTs to achieve higher energy efficiency levels. In addition to the new IH series, STMicroelectronics' gully gate Field Cutoff (TFS) IGBT series for soft switching includes HB and HB2 series for power supplies, welders and solar converters.
The STGWA40IH65DF and STGWA50IH65DF are rated at 40A and 50A respectively and are suitable for applications with a maximum power of 4kW. A low saturation voltage of 1.5V (VCE(sat))(typical at nominal current) and an internal low voltage drop diode give these advanced IGBTs excellent on-off performance and a low turn-off loss of only 0.19mJ (typical for the 40A STGWA40IH65DF).
The IH series IGBT has a maximum junction temperature of 175°C, low thermal resistance, and a positive VCE(sat) temperature coefficient for higher reliability. The STGWA40IH65DF and STGWA50IH65DF IGBT are now available in TO-247 long lead power packages. STMicroelectronics will introduce 20A and 30A products in TO-247 long lead package and TO-220 package in the near future.
