TVS/Steering Diode Array
The SR2.8 protects a two line pair, or four data or transmission lines. Rated at 2.8V and 5pF, it's ideal for low-voltage circuit applications where operating currents are less than 100mA. It has a leakage current of less than 1mA and is available in the SOT-143 package. It provides ESD (IEC 61000-4-2) and EFT (IEC 61000-4-4) protection. It is rated at 200W for a surge waveform of 8/20 µs.

The 1700V IGBT offers higher power integration in the same module housing. The IGBT trench cell with a field stop construction reduces on-state losses of IGBTs and dynamic losses. In combination with a reduced active area of the IGBT cell, a product line up to a 50% higher current range will be offered. The highest current carrying capacity will be the single-switch high-power module with 3600A nominal current.

The Maxwell 9.0 simulation environment solves complex electromechanical, power-electronic,and mechatronic system designs. It solves 3-D applications involving voltage or current sources with arbitrary waveforms important for the design of Non-Destructive Evaluation, MRI, and power-transformer equipment. It also calculates core loss, including the eddy current, excess and hysteresis loss of materials.
