TransGuard®Automotive Series
Multilayer Varistors for Automotive Applications
GENERAL DESCRIPTION
The TransGuard Automotive Series are zinc oxide (ZnO) based ceramic semicon-
ductor devices with non-linear, bi-directional voltage-current characteristics.
They have the advantage of offering bi-directional overvoltage protection as well as
EMI/RFI attenuation in a single SMT package. The Automotive Series high current
and high energy handling capability make them well suited for protection against
automotive related transients.
FEATURES
• High Reliability
• High Energy Absorption (Load Dump)
• High Current Handling
• AEC Q200 Qualified
• Bi-Directional protection
• EMI/RFI attenuation
• Multi-strike capability
• Sub 1nS response to ESD strike
APPLICATIONS
• Internal Combustion Engine (ICE) Vehicles
• Hybrid Electric Vehicles (HEV)
• Plug-in Hybrid Electric Vehicles (PHEV)
• Commercial Vehicles
– CAN, LIN, FLEXRAY based modules
– Sensors
– Module load dump protection
– Motor/inductive load transient suppression
