A transient voltage surge suppressor (TVSS) is an electrical device that protects electrical circuits and other sensitive electronic equipment from damage caused by excessive power surges. The MASMLJ28CAE3, a popular TVSS device, is a bidirectional suppressor that is designed to protect computer and telecommunications systems from short duration voltage transients. It has been rated for both ac and dc overvoltage protection, as well as cable protection and EMI/RFI protection.

The MASMLJ28CAE3 has a clamping voltage of 28V, with a maximum peak energy of 1.5 joules. It features a breakdown voltage of 8V maximum, a response time of 35ns maximum, a reverse leakage current of 200mA maximum, and an operating temperature range of -55°C to +125°C.

The MASMLJ28CAE3 offers protection against transients caused by electro-magnetic interference (EMI) and radio frequency interference (RFI) as well as overvoltage transients caused by line spikes, power surges, and more. It also has the capability to protect against charging surges generated by inductive switching. The MASMLJ28CAE3 is designed to be used in a variety of applications including computers, input/output ports for peripheral equipment, data lines, and other sensitive electronic devices.

The MASMLJ28CAE3 works by providing a short-circuit path between the power source and the device being protected. This short-circuit path helps to limit the voltage that can reach the device and protects it from damage caused by surges and transients. The unit also contains a reverse-biased avalanche diode that helps to limit the voltage that can reach the device. By limiting the voltage, the unit ensures that the device is not damaged by transients or power surges.

In addition to providing voltage-limiting protection, the MASMLJ28CAE3 also includes a built-in thermal fuse that helps to protect internal components from overheating. The unit also contains an LED indicator that can be used to indicate whether the device is working properly. This indicator helps the user determine if the device needs to be replaced. Finally, the MASMLJ28CAE3 is constructed with an epoxy case that helps to protect the unit from damage caused by environmental factors such as moisture, dust, and vibration.

The MASMLJ28CAE3 is a popular choice for the protection of sensitive electronic equipment from power surges. Its wide range of features makes it an excellent choice for a variety of applications. With its high surge capability, fast response time, thermally self-resetting fuse, LED indicator, and epoxy case, the MASMLJ28CAE3 is an effective and reliable choice for protecting sensitive electronic equipment from damage caused by excessive power surges.
