TVS (Transient Voltage Suppressors or Transorb) - Varistors, MOVs (Metal Oxide Varistors) devices are electrostatic devices mainly used for surge protection, signal line protection, and ESD protection. They can also be used for clamping and filtering, for example for high-speed signal lines. Each type of TVS device is defined according to its package and Maximum Stand-Off Voltage range. VC121085S151DP is one of the most popular TVS-Varistors, MOVs produced by Bourns.

VC121085S151DP is a surface-mount TVS device with a maximum stand-off voltage of 150V. It has a Lead-free, oxide-passivated, mov construction with no voltage handling limitations. With its low clamping factor of 1.04V, it is suitable for ESD protection. In addition, the VC121085S151DP features a low insertion loss of 0.9dB and wide frequency range of 0-1GHz. It also has a low leakage current of 15mA and a low impedance of 1.2ohms.

The VC121085S151DP can help protect signal lines from ESD and transient surges. It can also be used as a filter and clamp on high-speed signal lines. Its low insertion loss ensures that the signal integrity is maintained, and its low impedance offers superior protection. Other applications include telecom protection and instrumentation protection.

The working principle of VC121085S151DP is based on its mov construction. MOVs are high conductance, low-impedance material with a large reaction area during a surge. When subjected to a surge, they offer a low impedance path to divert the surge, thus ensuring protection. This low-impedance path also absorbs and dissipates the energy generated by the surge.

In summary, VC121085S151DP is a high performance surface-mount television suppressor or transorb with a maximum stand-off voltage of 150V. It has excellent features such as low clamping factor, low insertion loss, wide frequency range, low leakage current, and low impedance. Its mov construction offers superior surge and ESD protection, and its low impedance ensures signal integrity. The VC121085S151DP can be used in a variety of applications such as telecom protection and instrumentation protection.
