AVX released the TransGuard VT Series, presented as the first multilayer varistor (MLV) transient voltage suppression (TVS) devices rated for 175°C operation. The high-temperature MLVs provide reliable bidirectional overvoltage protection at operating temperatures from -55°C to 175°C with zero derating, are qualified to AEC-Q200, and are available in surface-mount 0603 and 0805 case sizes.
Providing some broadband EMI filtering in their off state, the devices reduce the need for discrete MLCC capacitors, and additional performance highlights include high current and energy handling capabilities, low leakage current, and multi-strike capabilities per IEC 61000-4-2. The zinc oxide-based ceramic semiconductor devices offer non-linear, bi-directional voltage-current characteristics similar to back-to-back Zener diodes, but with greater current and energy handling capabilities and EMI/RFI attenuation.
TransGuard VT Series high-temperature MLVs are compliant with the ESD performance requirements defined in the AEC-Q200, IEC 61000-4-2, and ISO 10605 standards and are currently offered as four standard parts with RoHS-compliant nickel barrier, 100 percent matte-tin-plated terminations.
