The SMDA24C-4E3/TR7 is a part of a line of Transient Voltage Suppressor (TVS) diodes family. This versatile device is designed to protect electrical circuitry from violent transients, also known as electrical overstress (EOS). It combines a matched series of avalanche diodes with a Zener diode in a single package. It delivers optimum performance and accurate protection to a wide variety of applications in harsh operating environments.

It is important to note that the TVS diode family is divided into two segments, unidirectional with a single anode and a cathode, and bidirectional diodes with two anodes and two cathodes. The SMDA24C-4E3/TR7 is a unidirectional TVS diode offering both EOS protection and voltage clamping in tough environments.

This SMDA24C-4E3/TR7 is available in a wide range of voltages, from 1.0V to 24V and is based on the Uni-Polar TVS, meaning it blocks voltage in only one direction - from the anode to the cathode. It is designed to prevent high voltage transients on systems or circuits, and can safely absorb peak pulse energies up to 30A and transient voltages up to 24V.

The SMDA24C-4E3/TR7 is particularly designed for ESD protection, in order to protect both public and personal safety from the dangers of ESD. It has an IEC 60529 IP Level 3-4 standard for dust, water, and oil resistance, making it ideal for applications where extreme environmental conditions exist. It also has excellent heat sinking and is capable of dissipating thermal energy of up to more than 10W/°C.

The SMDA24C-4E3/TR7 has a very low device capacitance and typical leakage current rating of less than 0.1pF at 5V and 1nA at 1V. The low capacitance of the device ensures that it will work with minimal interference in high frequency applications. Furthermore, the device also features an ultra-fast response time (less than 1ns) and a low clamping voltage to provide maximum device protection.

The SMDA24C-4E3/TR7 is designed for a variety of AC, DC and multi-pulse applications across numerous industries and applications. Its uses includes consumer and computer electronics, automotive, automotive lighting, telecommunication relay systems, robotics, industrial power systems, medical equipment, power supplies, and more.

The working principle of the SMDA24C-4E3/TR7 hinges on its EOS protection from high-voltage transients. The device works by clamping the applied transients to a low voltage level so that it can absorb the energy without damaging the system. When the transient voltage exceeds the device’s breakdown voltage, the avalanche diode is triggered and quickly conducts a high amount of current, which dissipates the energy and therefore limits the surge.

The SMDA24C-4E3/TR7 provides superior EOS protection and offers excellent protection from short-duration surges. It is an ideal replacement for conventional suppressors and other TVS devices in terms of size, performance and cost. Its superior features make it a preferred choice for a broad range of applications and industries, and an ideal choice for those looking for a reliable and effective way to protect their systems and components from transients.
