1 TEFONIX International Co. Ltd. INTERNATIONAL Company Profile Carrie Tsung May 31, 2006

2 INTERNATIONAL 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.

3 INTERNATIONAL 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--

4 INTERNATIONAL Product-SIDAC Reference Application --Silicon bilateral voltage triggered switch with greater power-handling capabilities-- Basic Sidac Circuit Typical High Pressure Sodium Lamp Firing Circuit

5 INTERNATIONAL Product-SIDAC Reference Application --Silicon bilateral voltage triggered switch with greater power-handling capabilities-- Ignitor Circuit (Low Voltage Input) Ignitor Circuit (Low Voltage Input) Xenon Lamp Flashing Circuit Xenon Lamp Flashing Circuit

6 INTERNATIONAL Product-SIDAC Reference Application --Silicon bilateral voltage triggered switch with greater power-handling capabilities-- Relaxation Oscillator Using a Sidac

7 INTERNATIONAL Product-SPD/OVP Features Bidirectional crowbar protection High repetitive surge capability Low capacitance Low leakage current Fast response time Surface-mount outline or Axial lead packages Main Applications Customer Premises Equipment (CPE) such as phone, modems and caller ID adjunct boxes T-1/E-1, ISDN, xDSL and VoIP transmission equipment Data lines and security systems Primary protection including main distribution frames, building entrance equipment and station protection modules --Surge Protective Device/ Telecommunication Overvoltage Protector--

8 INTERNATIONAL Product-SPD/OVP Reference Application --Surge Protective Device / Telecommunication Overvoltage Protector-- Basic CPE Protection ADSL Protection

9 INTERNATIONAL Product-SPD/OVP Reference Application --Surge Protective Device / Telecommunication Overvoltage Protector-- Pair Gain RT Protection

10 INTERNATIONAL Product Plan  Currently main focus are on SIDAC and SPD/OVP lines  Future product plan - Protection components: Gas Discharge Tube (GDT), Varistor, ESD components - Protection components: Gas Discharge Tube (GDT), Varistor, ESD components. - Thyristors: Triac, SCR.

11 INTERNATIONAL 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.

12 INTERNATIONAL 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  ON Semi -Divested from thyristor business in 2000, focus on power management ICs now.  Bourn, Shindengen

13 INTERNATIONAL 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).

14 INTERNATIONAL Benefits from Tefonix  Better price-performance than other brands in the market.  Offer Compatible Solutions as Major Brands in the market.  Experienced Team in IT Field More Than Ten Year.  Offer Flexible Production.  Provide Tailor-made Service.  Provide Prompt Response.

15 INTERNATIONAL Thank You! Thank You! TEFONIX International Co. Ltd.
