Advanced Circuit Protection Components Communications Applications Advanced circuit protection devices for overvoltage and overcurrent transient events. Only One Name Means ProTek’Tion™ Communication interfaces are vulnerable to a variety of transient voltage threats such as electrostatic discharge (ESD), cable discharge events (CDE) and lightning surge. These threats provide the system designer with the challenge to incorporate over-voltage protection that meets or exceeds circuit protection standards (see Table 1), while not degrading the transmission rate. Key parameters, such as working voltage, clamping voltage and capacitance, must be taken into consideration when CIRCUIT PROTECTION STANDARDS STANDARD PEAK SURGE VOLTAGE - V VOLTAGE WAVEFORM - µs PEAK SURGE CURRENT - A CURRENT WAVEFORM - µs Bellcore 250 2/10 500 2/10 GR-1089 1000 10/1000 100 10/1000 ITU-T-K20 & K21 4000 10/100 100 5/310 1500 10/160 200 10/160 IEC 61000-4-2 FCC Part 68 8kV Contact 15kV Air 1/60 ns 30 8/20 IEC 61000-4-4 2kV, 4kV 5/50 ns 40 8/20 IEC 61000-4-5 2kV, 4kV 1.2/50 ns 50, 100 8/20 Table 1 - Circuit Protection Standards choosing an overvoltage protection device. Device capacitance is often a decisive factor in higher data rate applications (see Table 2). A TVS diode, like other semiconductors, has an inherent capacitance. Capacitance is dependent on junction area, doping concentration and the voltage across the diode terminals. The reverse bias voltage is inversely related to device capacitance, as reverse bias increases the device capacitance decreases. As the doping concentration increases, the voltage rating of the diode decreases and device capacitance increases. On the other hand, devices with higher voltage values have smaller junction capacitance. Larger junction area relates to higher current handling capability. But as the device or junction size increases the device capacitance increases along with it. One of the characteristics of a capacitor is lower impedance to time varying signals. The higher the frequency of a signal, lower the resistance offered to it. So when a TVS diode is used in a high data rate application, the intrinsic device capacitance tends to attenuate the signal. Hence, when the device capacitance is large the attenuation suffered by the high frequency DATA TRANSMISSION RATES signal is greater.

The curve represents the approximate limiting frequency for the capacitance(y-axis). A device with a capacitance value below the curve should not have any appreciable attenuation for a given signal. To satisfy an ever-demanding market for greater safety and reliability of electronics, ProTek Devices continues to work with the major electronic equipment manufactures to develop next generation products that are protected with ProTek Devices circuit protection components.
