These TVS diodes are characterized by extremely LOW CAPACITANCE while at the same time retaining their HIGH SURGE capability, extremely FAST RESPONSE time and LOW dynamic resistance. The 8LC series consists of 8 monolithic bi-directional TVS diode arrays and is specifically designed to protect multiple or single data lines with each channel being electrically independent for multiple I/O port protection. This series will meet the surge requirements of IEC 1000-4-2 Level 4 (Formerly IEC 801-2), Human Body Model for air and contact discharge. FEATURES: l 500 watts Peak Pulse Power (TP = 8 x 20µs) l Transient protection for data, signal, and Vcc bus to IEC 1000-4-2 (ESD) & IEC 1000-4-4 (EFT) l Protects up to 8 bi-directional lines l Standoff voltages from 5 to 15 volts l Low capacitance for high speed interfaces l Low clamping voltage l ESD protection > 15kV MECHANICAL CHARACTERISTICS: l JEDEC MS-012AA small outline package (SOP) or l 16 pin DIP l Solder temperature: 265oC for 10 seconds l Readily solderable terminals APPLICATIONS: l ESD & surge protection for power lines & I/O ports l TTL and MOS Bus Lines l RS-232, RS-422 and RS-485 data lines l High speed logic l High speed data & video transmission SCHEMATIC:
Peak Pulse Power vs Pulse Time 8 x 20 Impulse Waveform Typical Application (Data line protection) Line 1 thru 4 0.1 100 1000 0.01 0.1 Pulse Duration (µs) Peak Pulse Power (kW) Preliminary Data Sheet Monolithic, Low Capacitance TVS Array TVA8LCXXX Series 0.5 x Ipp Ipp Peak Pulse Current (%) Time (µs) Differential Mode: Eight lines may be protected differentially (line-to-line) by connecting Inputs/Outputs at pins 1 - 16. Common Mode: Bi-directional protection of eight lines is achieved by connecting Inputs/Outputs at pins 1 - 8. Pins 9 - 16 are connected to ground. Note: Device is symmetrical so connections may be reversed to serve a specific application.
