SL05T1G Series Applications Background This family of surge protection devices (SL05T1 series) are designed to protect sensitive electronics such as 1 2 communications systems, computers, and computer 3 3 peripherals against damage due to ESD conditions or transient voltage conditions. Because of their low 2 1 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 surge Figure 6. protection which is basically based in the below theoretical An alternative solution to protect unidirectional lines, is to principle: • connect a fast switching steering diode in parallel with the Capacitance in parallel: CT = C1+C2+....+Cn SL05T1 series device. When the steering diode is • Capacitance in series: 1/CT = (1/C1)+(1/C2)+....+(1/Cn) forward−biased, the surge protection will avalanche and The Figure 5 shows the integrated solution of the SL05T1 conduct in reverse direction. It is important to note that by series device: 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 COMPENSATING Surge DIODE protection functionality or not. The Figure 7 shows the connection between the steering diode and the SL05T1 series device: Figure 5. SL05T1 DEVICE In the case that an over−voltage condition occurs in the I/O line protected by the SL05T1 series device, the surge protection is reversed−biased while the compensation diode is forward−biased so the resulting current due to the transient voltage is drained to ground. STEERING DIODE If protection in both polarities is required, an additional device is connected in inverse−parallel with reference to the Figure 7. first one, the Figure 6 illustrates the inverse−parallel Another typical application in which the SL05T1 series connection for bi−directional or unidirectional lines: 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
