Energy Absorption/Peak Current Capability
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 semiconducting grains combine to
absorb and distribute transient energy (heat) (Figure 10).
This dramatically reduces peak temperature, thermal
stresses and enhances device reliability.
As a measure of the device capability in energy handling and
peak current, the V26MLA1206A part was tested with
multiple pulses at its peak current rating (150A, 8/20
μ
s). At
the end of the test, 10,000 pulses later, the device voltage
characteristics are still well within specification (Figure 11).
