High Temperature +175C Automotive Series +175C Rated Varistors GENERAL DESCRIPTION AVX High Temperature 175C 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 singlehighly reliable device. Products have been tested, qualified, and specified to 175C and they do not require any derating over specified operating temperature range. GENERAL FEATURES APPLICATIONS +175C rated, with no derating Under hood CHARACTERISTICS High Reliability Down Hole Drilling Operating Temp.: -55 to +175C AEC Q200Qualified High temperature Automotive and Industrial Working Voltage: 18, 31Vdc Applications Bi-Directional protection Case Size: 0603, 0805 EMI/RFI attenuation ESD rated to 25kV (HBM ESD Level 6) HOW TO ORDER VT A7 0603 18 A 400 R P Varistor Temp Automotive Case Working Energy Clamping Package Termination D = 7 (1,000) P = Ni/Snplated Rated 175C Size Voltage Rating Voltage R = 7 (4,000) 400 = 42V 0603 18 =18Vdc A =0.1J T = 13 (10,000) 650 = 65V 0805 31 =31Vdc C =0.3J 670 = 67V ELECTRICAL CHARACTERISTICS I E V P V (DC) V (AC) V V VC I E LD I Cap Jump Diss.
