AVX Corporation, a manufacturer and supplier of advanced electronic components and interconnect, sensor, control, and antenna solutions, released a new series of high-temperature, glass-encapsulated multilayer varistors (MLVs) that are qualified to AEC-Q200, and rated for operating temperatures extending from 55°C to +150°C.
Made of zinc oxide (ZnO) based ceramic semiconductor devices with nonlinear, bi-directional voltage-current (V-I), TransGuard Automotive VGAH Series combine bi-directional overvoltage circuit protection and EMI/RFI filtering functions in an SMT device.
The series displays high current and energy-handling capabilities, sub-nanosecond (<1nS) response times to ESD strikes, multiple-strike capabilities, high energy absorption/load dump, low leakage, and solderability. Additionally, this product includes glass encapsulation for protection against harsh environments and processes, including acids, salt, and chlorine flux, and no derating requirements for energy.
Available in five chip sizes (1206, 1210, 1812, 2220, and 3220) with 16-31VDC working voltages, 40-57V clamping voltages, 0.6-13J energy ratings, 1.5-50J load dump energy, 200-1,800A peak current ratings, and 700-15,000pF capacitance, VGAH Series MLVs are suited for use in high-temperature, harsh-environment DC motor, pencil coil, local interconnect network (LIN) bus, electrical control unit (ECU), turbocharger, sensor, and relay applications in commercial, hybrid electric (HEV), plug-in hybrid electric (PHEV), and internal combustion engine (ICE) vehicles.
The new VGAH Series also have RoHS-compliant nickel-barrier-over-pure-tin (Ni/Sn) terminations, are compliant with the ESD performance requirements defined in the AEC-Q200, IEC 61000-4-2, and ISO 10605 standards, and are supplied on 7" or 13" tape and reel for automated placement. Lead-time for the series is currently 14 weeks.
