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: COMPENSATING DIODE 2 1 3 3 2 1 Figure 6. 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 effective 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: TVS Figure 5. 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: SL05T1 DEVICE STEERING DIODE Figure 7. 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: INPUT OUTPUT Figure 8. For optimizing the protection, it is recommended to use ground planes and short path lengths to minimize the PCB's ground inductance. www.onsemi.com 4 SL05T1G Series PACKAGE DIMENSIONS SOT-23 (TO-236) CASE 318-08 ISSUE AR D NOTES: 1.
