The SMAJ100A-E3/1 is a TVS (transient voltage suppressors) diode, often utilized to provide protection from transient voltage conditions such as those caused by electrostatic discharge (ESD). It consists of a bidirectional diode array, a pair of capacitors, resistors, and two shielded wires which are connected to the diode\'s anode and cathode. When the transient voltage rises above the pre-programmed threshold voltage, the diode opens and allows the current to flow from the anode to the cathode, letting the voltage drop back to its normal level.

The SMAJ100A-E3/1 is mainly utilized in very sensitive equipment such as medical tools and instruments, communication devices, and automotive parts that are exposed to harsh environment conditions. It is suitable for use in power eletronics circuits, as well as high voltages applications. Its superior clamping performance allows fast reaction to large voltage swings and reduces component damage. It also has low leakage, good temperature stability, and is capable of operating at higher temperatures than other TVS diodes.

The working principle of SMAJ100A-E3/1 TVS diode is relatively simple. It consists of two diodes that are connected back to back. When a transient voltage above the diode’s breakdown voltage is applied, current flows through the diode from anode to cathode. This allows the transient voltage to drop to a normal level. After the transient voltage has dissipated, the diode remains in the open mode until the current level drops below the reverse leakage current. Then the diode is able to recover to its original state.

In addition, the SMAJ100A-E3/1 is designed to provide surge current protection up to 100A peak pulse current and to sustain a voltage greater than 10V. This feature allows the diode to be used in many applications that require high-current transient protection. This includes applications such as power supply protection, DC-DC converters, and high speed data lines.

The SMAJ100A-E3/1 is a widely used TVS diode that provides superior over-voltage and ESD protection to various types of electronic circuits in both domestic and industrial applications. It has low leakage, good temperature stability, and low clamping voltage. The diode also has a very fast response time, making it well suited for use in harsh environment and high-voltage applications.
