High Temp. Automotive VT Series
+150°C and 175°C Rated Varistors
GENERAL DESCRIPTION
High Temperature 150/175°C Multi-Layer Varistors are designed for underhood and other high temperature
automotive or industrial applications. Parts are AEC-Q200 qualified.
They offer bi-directional overvoltage protection as well as EMI/RFI attenuation in a single SMT package. This
allows designers the ability to combine the circuit protection and EMI/ RFI attenuation function into a single
highly reliable device.
Products have been tested, qualified, and specified to 150/175ºC and they do not require any derating over
specified operating temperature range.
