TransGuard

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
