sl05t1g series www. onsemi.com 4 applications background this fam ily of tvs devices (sl05t1 series) are designed to protect sensitive electronics such as communications systems, computers, and computer peripherals against damage due to esd conditions or transient voltage conditions. because of their low capacitance value (less than 5 pf), they can be used in high speed i/o data lines. low capacitance is achieved by integrating a compensating diode in series with the tvs which is basically based in the below theoretical principle: ? capacitance in parallel: ct = c1+c2+....+cn ? capacitance in series: 1/ct = (1/c1)+(1/c2)+....+(1/cn) the figure 5 shows the integrated solution of the sl05t1 series device: figure 5. compensating diode tvs in the case that an over?voltage condition occurs in the i/o line protected by the sl05t1 series device, the tvs is reversed?biased while the compensation diode is forward?biased so the resulting current due to the transient voltage is drained to ground. if protection in both polarities is required, an additional device is connected in inverse?parallel with reference to the first one, the figure 6 illustrates the inverse?parallel connection for bi?directional or unidirectional lines: figure 6. 3 2 1 3 2 1 an alternative solution to protect unidirectional lines, is to connect a fast switching steering diode in parallel with the sl05t1 series device. when the steering diode is forward?biased, the tvs will avalanche and conduct in reverse direction. it is important to note that by adding a steering diode, the ef fective capacitance in the circuit will be increased, therefore the impact of adding a steering diode must be taken in consideration to establish whether the incremental capacitance will affect the circuit functionality or not. the figure 7 shows the connection between the steering diode and the sl05t1 series device: figure 7. steering diode sl05t1 device another typical application in which the sl05t1 series device can be utilized, is to protect multiple i/o lines. the protection in each of the i/o lines is achieved by connecting two devices in inverse?parallel. the figure 8 illustrates how multiple i/o line protection is achieved: figure 8. output input for optimizing the protection, it is recommended to use ground planes and short path lengths to minimize the pcb?s ground induc tance.
