VLAS series low-clamp TransGuard automotive-qualified multilayer varistors (MLVs) are designed to exhibit lower breakdown and clamping voltage to working voltage ratios.
Comprised of zinc-oxide-based ceramic semiconductor devices with nonlinear, bidirectional voltage current characteristics similar to those of back-to-back zener diodes, but with greater current and energy handling capabilities and addition of EMI/RFI attenuation. Combine bidirectional overvoltage circuit protection and broadband EMI/RFI filtering functions. Qualified to AEC-Q200. Extend multifunctional advantages of varistor technology to automotive, industrial and general electronics applications that require tighter clamping voltage performance for enhanced overvoltage protection, as well as extreme optimization of physical space, including infotainment systems, engine control units, microcontroller units and displays. Have high current- and energy-handling capabilities; fast sub-nanosecond (<1nS) response times to ESD strikes; multiple strike capabilities; high energy absorption (i.e., load dump); low leakage and solderability. Don’t require current or energy derating over rated operating temperatures spanning -55° to 125°C. Currently available in four chip sizes: 0603, 0805, 1206, and 1210. Rated for 16VDC working voltages, 35VDC maximum (30VDC typical) clamping voltages, 0.1J–1.6J energy ratings, 0.7J–3J load dump energy, 50A-500A peak current ratings, and 400pF-5,000pF capacitance.
