Transient voltage suppressors (TVS) are electromechanical components designed to protect electronic equipment from high energy voltage transients. These high energy transients are caused by lightning strikes, automobile jump starts, electrical arc faults, and electrostatic discharge.The SM2T27A is a commercially available TVS. This device is designed for use as a high surge current protecion in place of mechanical varistors, fuses, or other protective devices.

The SM2T27A application field includes high energy pulse spike or surge current protection in both AC and DC systems. It can be used for protection of small electronic components, remote control circuits, automotive and telecom systems. The SM2T27A is an ideal device for use in industrial, telecommunications, computer, and consumer electronics.

The SM2T27A is designed to limit surge currents and is a bidirectional device. It consists of an integrated circuit and an avalanche diode. The integrated circuit includes a direct breakdown device and a reverse blocking device. The direct breakdown device allows a controlled current to flow when a pulse that exceeds the breakdown voltage is applied. The reverse blocking device helps to protect against overvoltage.

The working principle of the SM2T27A is based on an avalanche breakdown effect. It has a rated breakdown voltage of 27V and a maximum peak pulse current of 2A. When an input voltage greater than the breakdown voltage is applied, the avalanche effect will begin by generating a large number of carriers that enable the current to flow through the device. This breakdown process generates a large amount of heat, which is then dissipated as a pulse of current through the device.

The SM2T27A is a reliable and cost effective device for surge current protection in both AC and DC systems. It provides robust protection against high energy transients and helps safeguard circuits and devices from damage due to excessive electrical transients. Additionally, the device is easy to install and requires minimal maintenance.
