TVS (transient voltage suppressor) or MOVs (metal–oxide varistors) are well known as the standard components for protection against transients in electronic systems and electrical systems alike. ROV07-270K-S-2 is a low-cost and high-performance varistor-type transient voltage suppressor (TVS) which can provide excellent protection against transient voltage surges. This protection is usually used for applications such as clamping/discharging, over-voltage/over-load protection, and ESD protection.

The ROV07-270K-S-2 has a capacitance value of 270pF and a typical breakdown voltage rating of 13.7V. It is designed for excellent clamping performance over a broad range of frequencies (up to 100Mhz), and provides over 1000W peak pulse current and 600V maximum surge voltage. The ROV07-270K-S-2 also has an integrated diode which allows for soft-clamping of over-voltage transients. This provides an additional layer of protection against voltage spikes which may be induced by lightning or other transient surges.

The primary application field covered by the ROV07-270K-S-2 is protection against ESD (electro-static discharge) and lightning-induced transients. These devices are ideal for industrial, automotive, telecommunications, consumer electronics, automotive, and other applications that are vulnerable to high transient voltages and are subjected to ESD events. This type of protection can be used in many places such as motors, electronic speed controllers (servos), and switch-mode power supplies.

The working principle of the ROV07-270K-S-2 is based on a varistor device which can conduct current in both directions (bi-directional). It works by using a metallic oxide varistor (MOV) with a breakdown voltage (BVR) characteristic. The MOV is connected between the power line and ground, with the varistor suppressing any over-voltage transients that may be present. When the suppression voltage is exceeded, the MOV is then activated and current begins to flow until the excessive voltage dissipates, thus providing protection.

In addition, the device also incorporates a diode to ensure soft-clamping and reduce over-voltage stress on the protected components. This allows for effective clamping of transients and reduces any associated stresses. The diode also helps with over-voltage protection as it prevents voltage spikes from flowing back into protected components which could potentially cause damage.

Overall, the ROV07-270K-S-2 from Triad Electronics is an excellent TVS device for protection against ESD and lightning-induced transients. Its bi-directional protection, low-cost and high-performance make it the ideal choice for a wide range of applications from industrial to automotive. It also provides effective clamping, over-voltage protection, and ESD protection, making it an optimal choice for protecting against damaging transients.
