V320LS20APX2855

TVS or transient voltage suppressors are electrical components used to protect electrical circuits from overvoltage and unwanted power surges. Varistors, or voltage-dependent resistors, are also used to protect circuits against overvoltage. MOVs or Metal Oxide Varistors are another type of surge protection devices used in electricity protection applications.

The V320LS20APX2855 device is manufactured by ROHM Semiconductor and it belongs to the MOV family of Varistors. It is a 350V rated, long-term-available 20mm disc varistor. It is intended to protect vulnerable components in a circuit by absorbing energy from transient surges and overvoltages, so that those components remain safe during abnormal voltages or power surges.

Application Fields

The V320LS20APX2855 device is widely used in a numerous of application fields, like for example SMPS, DC-DC converter and other industrial electronics, automotive and consumer circuits, solar cell systems, home appliances. Since it features various characteristics such as high surge capacity, fast response time, low leakage current, high temperature, and ESD tolerance, it enables designers to build reliable circuits with uncompensated design.

Working Principle

The working principle of the V320LS20APX2855 device is simple. It is a voltage-dependent resistor that reacts to overvoltage forces and absorbs the incoming energy. When a surge of voltage passes through the device, the device will provide a flow path for the current away from the nodes of the circuit and dissipates it as heat. This action helps to protect the circuit components from excessive voltage. The MOV\'s resistance varies according to the magnitude of the voltage, hence providing protection up to the rated volume.

The V320LS20APX2855 has high surge capability and can effectively absorb large amount of energy from transient surges and overvoltages. It also has a low clamping voltage which helps to protect sensitive electronic components from being damaged. Furthermore, the device is designed for RoHS compliant production and features an extended operating temperature range of -40 to +85°C.

The ROHM Semiconductor V320LS20APX2855 device is a high quality, long-term stable varistor designed for surge protection applications. With its wide range of features, high surge capacity and fast response time, it brings reliable protection to a range of circuits and components. It is ideally suited for use in applications that require enhanced ESD protection, including SMPS, DC-DC converter and other industrial electronics, automotive and consumer circuits, solar cell systems, and home appliances.
