In the non−latch up free load line case, the IV characteristic of the snapback protection device intersects the load−line in two points (VOPA, IOPA) and (VOPB, IOPB). Therefore in this case, the potential for latch−up exists if the system settles at (VOPB, IOPB) after a transient. Because of this, ESD8351 Series should not be used for HDMI applications – ESD8104 or ESD8040 have been designed to be acceptable for HDMI applications without latch−up. Please refer to Application Note AND9116/D for a more in−depth explanation of latch−up considerations using ESD8000 series devices. ON Semiconductor’s 8000 series of ESD protection devices utilize a snap−back, SCR type structure. By using this technology, the potential for a latch−up condition was taken into account by performing load line analysis of common high speed serial interfaces. Example load lines for latch−up free applications and applications with the potential for latch−up are shown below with a generic IV characteristic of a snapback, SCR type structured device overlaid on each. In the latch−up free load line case, the IV characteristic of the snapback protection device intersects the load−line in one unique point (VOP, IOP).

Diagram of ESD Clamping Voltage Test Setup The following is taken from Application Note AND8308/D − Interpretation of Datasheet Parameters for ESD Devices. systems such as cell phones or laptop computers it is not clearly defined in the spec how to specify a clamping voltage at the device level. ON Semiconductor has developed a way to examine the entire voltage waveform across the ESD protection diode over the time domain of an ESD pulse in the form of an oscilloscope screenshot, which can be found on the datasheets for all ESD protection diodes. For more information on how ON Semiconductor creates these screenshots and how to interpret them please refer to AND8307/D. ESD Voltage Clamping For sensitive circuit elements it is important to limit the voltage that an IC will be exposed to during an ESD event to as low a voltage as possible. The ESD clamping voltage is the voltage drop across the ESD protection diode during an ESD event per the IEC61000−4−2 waveform. Since the IEC61000−4−2 was written as a pass/fail spec for larger www.onsemi.com 5 ESD8351, SZESD8351 Transmission Line Pulse (TLP) Measurement L Transmission Line Pulse (TLP) provides current versus voltage (I−V) curves in which each data point is obtained from a 100 ns long rectangular pulse from a charged transmission line. A simplified schematic of a typical TLP system is shown in Figure 10. TLP I−V curves of ESD protection devices accurately demonstrate the product’s ESD capability because the 10s of amps current levels and under 100 ns time scale match those of an ESD event. This is illustrated in Figure 11 where an 8 kV IEC 61000−4−2 current waveform is compared with TLP current pulses at 8 A and 16 A. A TLP I−V curve shows the voltage at which the device turns on as well as how well the device clamps voltage over a range of current levels. 50 W Coax Cable S Attenuator ÷ 50 W Coax Cable IM 10 MW VM DUT VC Oscilloscope Figure 10.
