Varistor Datasheet

MLA Varistor Series

Surface Mount Multilayer Varistors (MLVs)

ClampingVoltage OverTemperature (VC at 10A)

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 106Ω at its maximum rated working voltage).

Leakage currents at maximum rated voltage are below 100µA,

typically 25µA; for 0402 size below 20µA, typically 5µA.

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.

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 ZNO dielectric

material is less 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.

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 (3A, 8/20µs). At the end of the

test,10,000 pulses later, the device voltage characteristics are still

well within specification.
