- Catastrophic SEE in High-Voltage Power MOSFETs
- This white discusses about the Heavy ion irradiation of high-voltage power MOSFETs with long-range ions (>123µm in silicon) which was performed using 14, 19, 22, 24, 28, and 39 MeV-cm2/mg ions at normal incidence. The paper reveals that prior to catastrophic failure some DUTs exhibited unusual electrical characteristic: all devices...

- An Electronic Ballast: Base Drive Optimization
- The transformer's auxiliary windings which provide base drive might contain just one or two turns each. In order to provide rapid transistor turn-off, their peak loaded output voltage would need to be such that the transistor 'sees' a turn-off voltage of around minus 5V. An approximation to this drive voltage...
