ROV20H911K

TVS ( Transient Voltage Suppressors) devices protect circuits from overvoltage transient events, such as ESD (electrostatic discharges) and lightning. They work by diverting excess voltage away from a circuit, thus limiting its potentially damaging effect. The ROV20H911K is a TVS device specifically designed for automotive use. It is an unidirectional TVS with a clamping voltage of 18 volts, rated for peak pulse power up to 1.5 kW and surge energy power of 2.8 joules.

As is common for all TVS devices, the ROV20H911K protects a circuit or component from voltage that exceeds its specifications, which would otherwise lead to malfunctions or damage. This can be caused by an outside source such as lightning or an ESD strike, or from internal sources such as induced voltages due to power supply level changes. The TVS device diverts excess voltage away from the protected circuit, thus limiting its effect, and allowing the protected circuit to continue working.

The ROV20H911K is specifically designed to protect against the harsh conditions in automotive applications. It is equipped with a robust, low-inductance component structure that ensures excellent clamping performance up to 18 volts, as well as high-temperature operation up to 150°C. It is also able to withstand sustained transients up to twice its rated voltage in the automotive environment.

The ROV20H911K is one example of a MOV (Metal Oxide Varistor) device that is commonly used in automotive applications for overvoltage protection. It is usually configured in a two-pin bridging configuration with two terminals connected to the component, and one connected to the protected circuit. When a transient voltage is detected, the device diverts the current away from the protected circuit and ensures that the voltage remains within the maximum allowable specifications. As its rating suggests, the ROV20H911K can handle peak pulse power up to 1.5 kW and sustained transients up to twice its rated voltage.

The ROV20H911K can also be used as an ESD suppression device. This is because it has a built-in capacitance structure which can provide protection from ESD strikes up to 8kV per waveform. This means that the device can serve as a buffer, allowing the protected circuit to remain unaffected by the ESD event. The ROV20H911K also comes with an integrated shorts protection circuit, which helps to protect the circuit from shorts caused by ESD strikes.

In conclusion, the ROV20H911K is a TVS device specifically designed for automotive use. It can withstand peak pulse power up to 1.5 kW and provide protection from ESD events up to 8kV per waveform. It is also equipped with an integrated shorts protection circuit, which helps to protect the circuit from shorts caused by ESD strikes. It is an unidirectional TVS device with a clamping voltage of 18 volts, rated for peak pulse power up to 1.5 kW and surge energy power of 2.8 joules. With its robust, low-inductance component structure, it can provide excellent clamping performance and high-temperature operation up to 150°C.
