Dynamic avalanche in bipolar power devices

WebThis device ensures a very low static and dynamic power consumption across the entire V CC range from 0.8 V to 3.6 V. This device is fully specified for partial Power-down applications using I OFF. The I OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. WebFeb 16, 2024 · To improve the dynamic behaviour of rectifier diodes he invented the fast, soft recovery SPEED-diode. He gave the first quantitative description of the dynamical avalanche mechanism limiting fast switching. From 1991 to 2001 he held a lecture on power devices at the TU Darmstadt, Germany.
