TVS – Diodes are important components for many microcontroller and logic circuits. SMDA15C-4/TR13 are electrostatic discharge (ESD) protection devices that protect connected equipment from voltage spikes, such as those caused by static electricity or lightning. These devices are an efficient combination of a voltage regulator and a TVS diode and are designed to protect integrated circuits from overvoltage.

Application Fields

SMDA15C-4/TR13 is commonly used in automotive electronics, such as automotive displays, infotainment systems and electronic control units. Other application fields are industrial systems , consumer electronics, and medical systems. No matter the application, SMDA15C-4/TR13 help protect integrated circuits by providing an adjustable clamping voltage, up to 15 Volts, that quickly dissipates the extra voltage, preventing it from damaging sensitive components.

Working Principle

The working principle of SMDA15C-4/TR13 is simple. When an overvoltage is applied to integrated circuits (due to lightning or EMI), it injects positive current into the circuit. The diode then quickly conducts the extra current, clamping the voltage and protecting the circuit from damage. The clamping voltage can be adjusted up to 15 Volts, allowing the TVS diode to react to sudden voltage changes or distortions across the range of the circuit.

SMDA15C-4/TR13 are designed to be a small, lightweight, and easy-to-install solution for overvoltage protection. These devices come in small packages, requiring minimal board space, and are available with either thru-hole or SMT (surface mount technology) packages, depending on the customer\'s needs. They are also designed to operate at a wide range of temperatures, from -40°C to +125°C, so they can be used in harsh environments as well.

Overall, SMDA15C-4/TR13 are an effective and efficient solution for electrostatic discharge (ESD) protection in a variety of applications. They provide a robust and reliable voltage clamp that reacts quickly to sudden voltage surges, while taking up minimal board space. Additionally, they are designed to operate at a wide range of temperatures, making them a perfect solution for harsh environments.
