AVX has developed the sub pF varistor (SPV) solution for circuits with capacitance sensitivity. The VCH series is the latest addition to the AntennaGuard series of low capacitance TransGuard® products. SPV is a bi-directional transient voltage suppressor that was developed to provide a one chip solution for protecting high speed digital interfaces, RF antenna and RF amplifier circuits against ESD events.

Placing a transient suppressor in a signal line introduces the TVS’s parasitic capacitance. This parasitic capacitance can integrate the rise time and fall time of any signal and inject other types of distortion on the signal.

Minimizing the parasitic capacitance will maximize the signal speed and minimize the signal distortion.

The SPV product offers designers the ability to clamp transients with minimal loading & distortion to the circuit. The low profile 0402 and 0201 sizes offer designers flexibility in board placement.
