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.
At or below the maximum working voltage, the suppressor
is in a high resistance modex (approaching 10
maximum rated working voltage). Leakage currents at
maximum rated voltage are below 100μA, typically 25μA;
for 0402 size below 20μA, typically 5μA.
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 Z
than 1ns and the MLA can clamp very fast dV/dT events
such as ESD. Additionally, in "real world" applications,
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.

Energy Absorption/Peak Current Capability
Energy dissipated within the MLA Series 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 semiconducting grains
combine to absorb and distribute transient energy (heat)
(see Speed of Response). This dramatically reduces peak
temperature; thermal stresses and enhances device
reliability.
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.
