Device Characteristics

ClampingVoltage OverTemperature (V_Cat 10A)

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 ML 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 Z_NO dielectric material is less

than 1ns and the ML 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 (150A, 8/20μs). At

the end of the test,10,000 pulses later, the device voltage

characteristics are still well within speciﬁcation.
