Integrated Over Voltage Protection Circuits for Power Transistors
2006 IEEE International Symposium on Power Semiconductor Devices & IC's, 2006Nowadays, MOSFET and IGBT power components are widely used in medium and high power converters. They are subjected to increasing requirements: electrical performances, simple implementation, reliability, integration, smaller volume and price. Moreover, their integration process offers the possibility to reduce or eliminate the need for pick and place ...

A Compact Over-Voltage Protection Circuit for HBT Power Amplifiers
2006 IEEE MTT-S International Microwave Symposium Digest, 2006This paper presents an over-voltage protection circuit with low capacitance loading and small size. Its operation principles and measured performance will be presented. As a case study, a 5.4-6.0 GHz InGaP/GaAs HBT power amplifier with this compact over-voltage protection circuit, resulting in no degradation in PA performance, is demonstrated.

Aging of the over-voltage protection components
2002 23rd International Conference on Microelectronics. Proceedings (Cat. No.02TH8595), 2003The aim of this work was to examine the influence of the number of activations, i.e. over-voltage pulses, on the aging of over-voltage protection elements. Both nonlinear (gas-filled surge arresters (GFSA), varistors, over-voltage diodes), and linear (capacitors-constituents of filters) over-voltage protection elements were tested. The instruments used

Over-Voltage Protection Epoxy-CNT Composites
2019 International Conference on Electronics Packaging (ICEP), 2019The electronics industry is always looking for new ways of protecting devices from over-voltage, or over-current scenarios. In the present work we will introduce novel low-voltage epoxy-carbon nanotube composites with high non-linearity values in resistive devices. Some of the non-linearities achieved had alpha values greater than 10.
