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
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.
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.

Energy Absorption/Peak Current Capability
Energy dissipated within the MLA Automotive 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
grains combine to absorb and distribute transient energy
reliability.
As a measure of the device capability in energy and peak
current handling, the V26MLA1206 part was tested with
the end of the test,10,000 pulses later, the device voltage
characteristics are still well within specification.
