Transient Voltage Suppression (TVS) is an important component for the protection of electronic circuits. There are three main types of devices commonly used to protect circuit designs from short-term voltage spikes, known collectively as TVS devices: Varistors, Metal Oxide Varistors (MOVs) and Surge Protective Devices (SPDs). The BSPM1240S2G is a TVS device based on MOV technology, and it is commonly used in many different applications. This article will provide an overview of the BSPM1240S2G, its application fields and working principle.

BSPM1240S2G Application Fields

Due to its robust construction and efficient performance, the BSPM1240S2G is suitable for many applications, including automotive, industrial, telecom, lighting, home appliance and medical. Its low leakage current, high peak surge current rating, fast response time and small form makes it an ideal solution for circuit protection in a wide variety of devices.

The BSPM1240S2G can provide protection for signals, communication lines and other components in automotive, telecom and medical devices. Its performance in screening out voltages and EFT enables it to protect a range of components, from resistors and capacitors to transformers and logic circuits. In addition, the BSPM1240S2G is capable of providing surge protection in designs where other MOVs or TVS diodes are unable to provide sufficient voltage clamping, thus making it suitable for a number of industrial applications as well.

BSPM1240S2G Working Principle

The BSPM1240S2G utilizes Metal Oxide Varistor technology to provide transient voltage protection. The device is made up of a zinc oxide disc covered with a metal coating. When an electrical signal is applied to the device, the metal coating conducts the current and releases the energy of any transients. The high electrical resistance of the zinc oxide disc prevents the current flowing through the device from reaching unsafe levels.

If the voltage across the device exceeds its Voltage Clamping Level (VCL) threshold, the zinc oxide disc will break down and the device will start to conduct the current, thereby protecting the circuit from high electrical voltages. This process is known as “Clamping”. The result is that any transients passing through the device are shunted into the ground and the current is dissipated as heat.

In addition to its clamping capability, the BSPM1240S2G offers another function known as “Suppression”, which involves the use of a silicon controlled rectifier (SCR) to limit the flow of current through the device. This feature can be used to protect sensitive circuits from transients, as the SCR will activate if the voltage across the device exceeds a certain threshold and interrupt the current flow.

The BSPM1240S2G has a high surge current rating, the ability to limit both ESD and EFT protection, and an fast response time, making it suitable for many different application fields. Its robust construction and small form factor also make it a great choice for circuit protection designs.
