BSPM3480WYG

TVS (transient voltage suppressor) Varistors, MOVs (metal oxide varistors), also known as transient voltage suppressors, are an important component of of electrical engineering which are designed to help protect electrical components from voltage spikes and other transient voltage events. The BSPM3480WYG surface mount varistor is a good example of this type of electrical component.

The BSPM3480WYG is a voltage dependent over-voltage protection component designed to absorb and dissipate transient voltage spikes. It is most commonly used in circuit protection and overvoltage protection applications and provides a cost-effective solution for these applications. It has a profile of 18.2mm x 18.2mm, and can dissipate up to hundreds of watts of power in the event of a surge. The device is rated for a maximum allow voltage of 400V AC or DC and features a max pulse voltage capability of 4800V. It is available in a variety of leadbeaning options and may be used in high temperature and humidity conditions.

The working principle of the BSPM3480WYG is simple. It features a cylindrical zinc oxide element which contains zinc oxide granules. During normal conditions, these granules remain uncharged and remain in a solid state. When a surge or transient voltage occurs, the granules become electrically charged and form a conductive bridge. This bridge helps dissipate the surge energy away from the protected components, resulting in a low impedance “short circuit” which helps reduce the voltage across the device to more manageable levels. Once the transient event has passed, the granules return to their original state.

The BSPM3480WYG can be used in a variety of applications, such as:

• Lighting fixture over voltage protection
• Automotive circuit protection
• Telecommunications, telecom and cable equipment overvoltage protection
• Industrial motor and control systems protection
• Consumer and home electronics overvoltage protection
• Power supplies, electricity generation systems, inverters and solar systems protection

The BSPM3480WYG is well-suited for applications in which voltage spikes must be silenced and the components it is protecting must be safe from surges and transient voltage spikes. It features a robust, low-profile design suitable for high-temperature and humidity conditions and is available with a variety of leadbeaning options. In combination with its simple and effective working principle, it is a dependable and cost-effective solution to help protect vital electronics from transient voltage spikes and other dangerous voltage incidents.
