The AUML suppressor is manufactured from semiconducting
ceramics which offer rugged protection and excellent
transient energy absorption in a small package. The devices
are available in ceramic leadless chip form, eliminating lead
inductance and assuring fast speed of response to transient
surges. These Suppressors require significantly smaller
space and land pads than Silicon TVS diodes, offering greater
circuit board layout flexibility for the designer.
Also see the Littelfuse ML, MLN and MLE Series of
Multilayer Suppressors.
