Infineon Intros IGBT TrenchStop/FieldStop Technology

Infineon Technologies AG (Nuremberg, Germany) announced a new generation of its IGBT product family for the 1,200V voltage range that combines TrenchStop and FieldStop technology. The new IGBTs reduce conduction losses by up to 40 percent while exhibiting low switching losses. Optimized for switching frequencies up to 10kHz in hard-switching topologies, or up to 30kHz in resonant-switching topologies, the products are suitable for industrial motor drives, frequency converters, robot controllers and uninterruptible power supplies.

The new 1,200V IGBTs in the TrenchStop technology enable reduced conduction losses up to 40 percent. The FieldStop structure within the power semiconductor ensures a significant reduction in the tail current that occurs during high-speed switching, and at the same time, the TrenchStop cell limits conduction losses to a minimum due to the extremely low saturation voltage. As a result, less heat is generated and the cooling requirement is reduced, leading to a lower system cost.

Infineon's new family of 1,200V TrenchStop IGBTs in the advanced TO247 package currently comprises five single versions for output currents from 8A to 55A, or 16A to 100A, plus four versions in the DuoPack package for output currents from 8A to 40A, or 16A to 80A. The DuoPack, which includes the anti-parallel EmCon diode with a TrenchStop IGBT device, enables low-cost solutions in applications requiring a reverse diode.

All versions of the 1,200V TrenchStop IGBTs are available in volume quantities. In quantities of 1,000 units, the price per unit is less than $2.50 for 15A single versions in the TO247 package, and less than $3.00 for 15A DuoPack versions in the TO247 package.
