Device Characteristics  
At low current levels, the V-I curve of the multilayer transient voltage  
suppressor approaches a linear (ohmic) relationship and shows a  
temperature dependent effect (Figure 10). At or below the maximum  
working voltage, the suppressor is in a high resistance mode (approach-  
ing 106at its maximum rated working voltage). Leakage currents at  
maximum rated voltage are below 50µA, typically 25µA; for 0402 size  
below 10µA, typically 5µA.

Energy dissipated within the ML is calculated by multiplying the clamping  
voltage, transient current and transient duration. An important advantage  
of the multilayer is its interdigitated electrode construction within the mass  
of dielectric material. This results in excellent current distribution and the  
peak temperature per energy absorbed is very low. The matrix of semicon-  
ducting grains combine to absorb and distribute transient energy (heat)  
(Figure 11). This dramatically reduces peak temperature; thermal stresses  
and enhances device reliability.

Speed of Response  
The Multilayer Suppressor is a leadless device. Its response time is not  
limited by the parasitic lead inductances found in other surface mount  
packages. The response time of the Zinc Oxide dielectric material is less  
than 1 nanosecond and the ML can clamp very fast dV/dT events such  
as ESD. Additionally, in real worldapplications, the associated circuit  
wiring is often the greatest factor effecting speed of response. Therefore,  
transient suppressor placement within a circuit can be considered  
important in certain instances.  
As a measure of the device capability in energy and peak current  
handling, the V26MLA1206A part was tested with multiple pulses at its  
peak current rating (150A, 8/20µs). At the end of the test, 10,000 pulses  
later, the device voltage characteristics are still well within specification  
(Figure 13).
