TVS - Varistors, MOVs are primarily used to protect sensitive electronic circuits against transient surge/voltage phenomena causing over-voltages. These surges are mainly from electrical phenomena like lightning, switching transients, and other over-voltages of various forms that can be traced back to electrical power sources. The BSPM2275TN is one of the most reliable and efficient Varistors, MOVs available in the market for providing an appropriate form of protection for sensitive electrical circuits.

The BSPM2275TN is a bidirectional, transorb type, thermally protected, Metal-Oxide Varistor (MOV). The MOV body is composed of zinc oxide molded in an epoxy case with stainless-steel caps. It is designed to offer superior protection to delicate circuits against static over-voltages caused due to transients. It is capable of clamping voltages both negative and positive. Its varistor voltage rating is 225Vrms & 275Vdc and its clamping voltage is at 390Vpeak.

The BSPM2275TN application field includes Line Interface Protection, Industrial Equipment, Telecom systems, Consumer Application, and Automotive. It provides advanced protection against electro-magnetic interference (EMI) and radio frequency interference (RFI). The operating temperature ranges from -40°C to +85°C which is ideal for outdoor applications. Its fail-short feature makes sure that the circuit’s primary protection remains intact in the event of a varistor failure.

The BSPM2275TN working principle is based on a four-layer construction of metal-oxide grains of alloy-grade zinc oxide, spark-erosion bonds, and a over-molded epoxy case. The combination of these layers provides excellent performance in clamping transients and peak pulse currents. As an over-voltage condition occurs, the voltage across the Metal-Oxide Varistor (MOV) increases exponentially. This increase in voltage continues until the voltage reaches a level which is close to the maximum voltage rating of the MOV. This causes the varistor to rapidly conduct large currents which clamps the over-voltage, thus providing protection.

The BSPM2275TN also offers other features such as high temperature stability, resistance to humidity, and low reverse leakage current. It is also RoHS compliant which makes it a suitable alternative for many applications.

In conclusion, the BSPM2275TN is an ideal Varistor, MOV for providing protection to sensitive electrical circuits. It is capable of clamping voltages both negative and positive and offers superior protection against static and dynamic over-voltages caused due to transients. Its operating temperature ranges from -40°C to +85°C which makes it suitable for outdoor applications. It also provides other features like high temperature stability, resistance to humidity, and low reverse leakage current. It also offers an advanced protection against electro-magnetic interference (EMI) and radio frequency interference (RFI). Therefore, BSPM2275TN is a great choice of Varistor, MOV available in the market.
