BSPM2240S3G: TVS - Varistors, MOVs Application Field and Working Principle TVS (Transient Voltage Suppressor) is an electronic component that can provide protection for circuits from voltage-induced damage, which is rarely encountered on printed circuit boards. Among the many families of TVS components, the MOVs (Metal Oxide Varistors) and varistors are the most commonly used and are both part of the BSPM2240S3G product family. The BSPM2240S3G is a bidirectional, unidirectional, and symmetrical TVS diode that can provide protection against multiple sources of electrical stress. This device is suitable for consumer products, industrial applications, and other environmentally sensitive equipment where reliable transient protection is required. The BSPM2240S3G has a reverse breakdown voltage of 240V and a forward I-V curve of 10A. It is able to suppress transient and ESD spikes with peak pulse current exceeding the maximum I-V figure.The working principle of the BSPM2240S3G is based on the Metal Oxide Varistor (MOV) technology. The MOVs are built on a sandwich structure consisting of two electrodes on either side of a ceramic layer containing zinc oxide varistor grains. The ceramic layer has a resistance that increases with increasing temperature while being less than 100 Ohms at room temperature. When a voltage higher than the breakdown voltage is applied across the varistor, the grains expand and form a conduction path that acts as a short-circuit between the electrodes.In between the electrodes, the varistor grains become heavily doped with carriers which create a low resistance channel for the current to flow through the device. The low resistance of the varistor channel is responsible for the surge current capability of the device, allowing it to absorb surge current up to a certain amount. This protection prevents the surrounding components from incurring damage from the surge. In addition, the BSPM2240S3G offers another level of protection for highly sensitive circuits by providing transient overvoltage protection. The specifically designed BSPM2240S3G has a peak pulse current of 10A, which makes it ideal for protecting consumer electronics, telecom equipment, and industrial equipment from transient overvoltage conditions. The BSPM2240S3 also offers low clamping voltage, fast response time, and flexibility towards size, voltage, and current ratings. Depending on the application and needed level of protection, the BSPM2240S3 can be used in various types of equipment such as air conditioners, electric meters, computers, industrial control systems, typewriters, power supplies, circuit boards, and cell phones. Furthermore, the device can be used to protect automotive electronics, adsl modems, and power supplies from surge-induced transients or ESD (Electrostatic Discharge) events. In conclusion, the BSPM2240S3G is a perfect choice for providing protection against transient overvoltage conditions, ESDs, and surge currents. Its superior design offers high surge current capability and low clamping voltage for a wide range of different applications. The device is available in a variety of voltages and current ratings, as well as a variety of sizes, making it suitable for almost any application.
