Transzorb Diodes, also known as TVS, are a common surge protection component used in many electronic circuits, particularly in high power applications.

The 3.0SMCJ100ATR is a device designed specifically for protection against high-speed spikes and transients. It is a bidirectional, transient voltage suppressor which has two components internally. The first component is a fixed multi-layer diode (MLD) array, which is responsible for trimming and limiting the spike. The second component is an integrated relay which provides negotiation of the voltage during a transient event. This combination of two components within the TVS provides extra protection than single-component devices.

The 3.0SMCJ100ATR offers several advantages over traditional avalanche diode or thyristor-based TVS devices. First, it is capable of operating under multifarious conditions, with its pulse waveform capability being sustained even at higher temperatures. Second, its electrical properties remain constant over a wide range of operating temperatures and frequencies. Third, it is highly reliable due to its choice of components, the MLD array and an integrated relay, which improve the protection given to the circuit. Its low capacitance and reverse leakage current are also beneficial factors in its operation.

The 3.0SMCJ100ATR is frequently used in automotive, industrial and consumer electronics applications. It provides protection against high voltage electrical spikes and transients, which can occur due to a range of electrical disturbances such as load switching in the power or motor circuit, power line transients, electrostatic discharge, etc. This device can also be used in combination with MOVs (Metal-Oxide Varistors) in motor control and switch mode power supplies.

The working principle of the 3.0SMCJ100ATR is simple enough to understand. It operates by a process of ‘clamping’, whereby a limiting voltage is applied across the device in order to prevent further voltage rise. The threshold of this limiting voltage (or clamping voltage) is determined by the multi-layer diode (MLD) array inside the device, and thus, the device is able to clamp the voltage even during an extremely rapid spike. The integrated relay ensures that the voltage is rapidly brought back to a normal value after the transient. The combination of the two components ensures that the device is able to maintain a high resistance to transients, while still offering excellent reliability and long-term protection.

Overall, the 3.0SMCJ100ATR is an excellent choice for voltage spike and transient protection, offering high-performance over a wide range of operating conditions. Its combination of MLD and relay ensures excellent reliability and long-term protection, making it well-suited to a wide range of automotive, industrial and consumer electronics applications.
