Multilayer Transient Voltage Surge Suppressor
AUML Varistor Series
The AUML Series of Multilayer Transient Surge Suppressors was specifi-
cally designed to suppress the destructive transient voltages found in an
automobile. The most common transient condition results from large
inductive energy discharges. The electronic systems in the automobile,
e.g. antilock brake systems, direct ignition systems, engine control,
airbag control systems, wiper motor controls, etc., are susceptible to
damage from these voltage transients and thus require protection. The
AUML transient suppressors have temperature independent suppression
characteristics affording protection from -55^oC to 125^oC.
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.
