Multilayer Varistors

The TransGuard® and StaticGuard VCLD Series multilayer varistors from AVX Corporation have Sn/Pb terminations, featuring a minimum of 5% lead (Pb).  Designed specifically to support customers who cannot accept pure tin components in their applications, especially within the defense industry, the new VCLD Series varistors provide EMI/RFI attenuation and bi-directional overvoltage protection against transient events such as ESD, inductive switching, lightning, and nuclear electromagnetic pulses (NEMP) in a single SMT package.

Featuring extremely fast response times to ESD strikes, multi-strike capabilities, high reliability, radiation resistance, and EMI/RFI filtering in the off-state, the new TransGuard® and StaticGuard VCLD Series multilayer varistors with Sn/Pb terminations are rated for use in temperatures spanning  -55 °C to +125 °C and are ideal for applications including: IC protection, micro controllers, relays, I/O ports, keyboard protection, portable devices, and radios, among others.

TransGuard® VCLD Series varistors are available in four cases sizes (0603, 0805, 1206, and 1210), 16 working voltages (spanning 5.6 VDC to 85 VDC), 13 energy ratings (spanning 0.05 J to 2.0 J), and 19 clamping voltages (spanning 18 V to 150 V).  StaticGuard VCLD Series varistors feature a working voltage of 18 VDC, a clamping voltage of 50V, and are availble in three case sizes (0603, 0805, and 1206) and two energy ratings (0.05 J and 0.1 J).  Additional physical and electrical characteristics can be achieved by contacting AVX to request SnPb terminations for its other varistor series.
