Abstract

The design rule for 8.5kV LTT was discussed here. An inherent integrated breakover diode (BOD) for self -protection function and multi-amplified gate (AG) for improved di/dt capability of LTT was introduced in principle. The trade-off between light triggering input source and high dV/dt limitation has been treated via narrow grooved P-base for gate design. Key process technology for LTT was given, too.
