TVS diodes are components used for protecting sensitive device circuits from electrical overstress. The PESD15VL1BA,115 is a unidirectional TVS diode suitable for IEC 61000-4-2 (ESD) protection, offering industry-leading performance with an ultra-low impedance of ≤ 0.2 Ohms from 3V to 15V.

The PESD15VL1BA,115 is designed using advanced low capacitance silicon-avalanche technology, enabling excellent clamping capability in the range of 3-15V. This allows excellent protection for sensitive electronic components that typically have voltage ratings of between 5V and 15V. The PESD15VL1BA,115 also offers excellent surge protection (IPP = 11.5A) capability for IEC 61000-4-2 (ESD) protection and is suitable for applications such as industrial, automotive and high energy.

The working principle of the PESD15VL1BA,115 relies on the ability of its interconnects (typically only 1 or 2) to carry enough current to trigger avalanche breakdown of its PN junction, dissipating the applied voltage and reducing the peak current. When an overvoltage event occurs (due to an electrostatic discharge, electrical surge, short circuit, or other overvoltage condition), the P-N junction is reverse biased and the voltage increases across it until it reaches its breakdown voltage, at which point the current sharply increases. This increases the power dissipation in the element, which helps to limit the voltage at the protected circuit.

The TVS diode has various uses in modern electronics, and the PESD15VL1BA,115 is just one example of this. It is suitable for a wide variety of applications, particularly those in industrial, automotive and high-energy environments, due to its excellent protection and low capacitance. Some of the common applications for this device include protection of control systems, communication systems, consumer electronics, and industrial or automotive infrastructure.

In conclusion, the PESD15VL1BA,115 is a unidirectional TVS diode designed with leading performance and low capacitance silicon-avalanche technology, offering industry-leading IEC 61000-4-2 (ESD) protection. Its ultra-low impedance of ≤ 0.2 Ohms from 3V to 15V makes it suitable for a wide variety of applications and environments, including in industrial, automotive and high-energy areas.
