  • 640 - Characteristics and Application SAC is a Transient Voltage Suppressor Diode in series with a compensation diode for low capacitance. Transient Voltage Suppressors may be used at various points in a circuit to provide various degrees of protection. Transient Voltage Suppressor provides excellent clamping capability. Since the low incremental surge resistance. For telecommumication : multi-protocol serial transceivers. Please refer as below: -) Cellular -) Universal series bus (USB) port production. -) Instrumentation. -) LAN / WAN equipment. -) Peripherals. -) High speed data lines. Tow devices are used in parallel and opposite polarity for protecting one bi-directional ines (FIG. 1), or with a steeling diode for protecting one unidirectional (FIG. 2). The low capacitance TVS series are used on high speeded interfaces such as video line, I 2C RS-485, RS-422 and USB, for ESD protection the lines which have signal, or data. Please refer as below: 1). Token Ring 2). I2C FIG. 1 FIG. 2 3). Video line 4). Set top box I/O 5). LAN / WAN equipment. 6). Security system 7). Automatic teller machine 8). HFC system 9).
