Company Profile Carrie Tsung May 31, 2006
About Us • Headquarter located in Taiwan • Dedicated in thyristors that apply in power-handling and surge protection. • SIDAC (silicon bilateral voltage triggered switch) performs better power-handling function. • SPD (Surge Protective Device), or called OVP: (OverVoltage Protector) to maintain better surge protection ability.
Product-SIDAC Features • Symmetrical characteristics • Designed for direct interface with AC circuit • Glass-passivated junctions insure reliable operation • High pulse current capability • Surface-mount or Axial lead packages Main Applications • Pulse generating circuits • AC switching circuits • Overvoltage protection circuits --Silicon bilateral voltage triggered switch with greater power-handling capabilities--
Product-SIDAC --Silicon bilateral voltage triggered switch with greater power-handling capabilities-- Reference Application Basic Sidac Circuit Typical High Pressure Sodium Lamp Firing Circuit
Product-SIDAC --Silicon bilateral voltage triggered switch with greater power-handling capabilities-- Reference Application Ignitor Circuit (Low Voltage Input) Xenon Lamp Flashing Circuit

Product Plan • Currently main focus are on SIDAC and SPD/OVP lines • Future product plan - Protection components: Gas Discharge Tube (GDT), Varistor, ESD components. - Thyristors: Triac, SCR.
Market Status • TVS diodes appeared in the early 80’s as the first practical semiconductor solution to surge protection. • In late 80’s and early 90’s, the SIDAC technology of thyristor products has been identified as a candidate for the primary surge protection device that telephone industry searched for. • SIDAC thyristor has found a new market needs in mid 90’s because of fast growth in Internet, multimedia, computer, auto industry and consumer electronics with surge sensitive circuitry. • Currently there are more governing agencies of health, safety, consumer and others are mandating the requirement of surge protection on all electronic equipment under Transient Immunity Standards.
Market Status • ST Microelectronics -Started in thyristor business by buying TAG, strong in Europe. -The thyristor business occupies small share and with weaker support. • Teccor (LittelFuse) -Wholly owned subsidiary of Company “Siebe”, specializing in thyristor products. -Has been merged by LittelFuse in 2003. • ON Semi -Divested from thyristor business in 2000, focus on power management ICs now. • Bourn, Shindengen
Recognition from Customers • Our product SPD/OVP has been used in the United States instead of Littelfuse, Teccor. • Our product SPD/OVP has been used in the United States instead of Bourn. • Our product SPD/OVP has been used in Taiwan (modem router and power protection socket). • Our product SIDAC has been used in Japan instead of Shindengen (air cleaner). • Our product SIDAC has been used in Malaysia instead of Shindengen (lamp). • Our product SIDAC has been used in Taiwan (air cleaner and igniter).
