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. 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 systems such as cell phones or laptop computers it is not clearly defined in the spec how to specify a clamping voltage % OF PEAK PULSE CURRENT 100 PEAK VALUE IRSM @ 8 ms tr 90 PULSE WIDTH (tP) IS DEFINED AS THAT POINT WHERE THE PEAK CURRENT DECAY = 8 ms 80 70 60 HALF VALUE IRSM/2 @ 20 ms 50 40 30 tP 20 10 0 0 20 40 t, TIME (ms) 60 Figure 10. 8 X 20 ms Pulse Waveform www.onsemi.com 4 80 ESD5581 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 11. 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 12 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 10 MW IM VM DUT VC Oscilloscope Figure 11.
