A Transient Voltage Suppressors (TVS) diode, also known as a Transorbs® diode, is a semiconductor device specifically designed to protect electrical and electronic systems from damage caused by voltage spikes or transients. The 15KP40A is a widely used TVS diode that is effective in transient suppression from lightening, ripple noise, switching noise, and other over-voltage occurrences. The 15KP40A is capable of providing rugged protection to circuits against ESD (Electrostatic Discharge) up to 30 kV as well as offering a low capacitance line that minimizes the disturbance of high-speed signals. This diode has a maximum peak pulse power rating of 40A and its peak pulse current rating is 18A.

The 15KP40A TVS diode is typically used to protect vehicles, aviation, high-end consumer electronics, networking equipment, industrial electronics, and automotive systems from electrostatic discharge (ESD). It is suitable for use as a primary line side clamp for insertion into data lines in order to provide ESD protection. The 15KP40A is available in numerous packages, such as surface-mount and leaded, which makes it a versatile choice for many applications.

The 15KP40A TVS Diode works by diverting excess current away from critical circuits or components while allowing normal current to flow uninterrupted. This diode acts as a protective or a safety valve, allowing a significant amount of current to flow when a transient voltage spike occurs. Under normal circumstances, the diode has a low impedance enough to allow a small, continuous flow of current. As the voltage increases to a certain level, the diode turns on, dissipating the excess energy and preventing any further damage. This switching action is referred to as “avalanche breakdown”.

The 15KP40A has a breakdown voltage of 15V and can hold up to 40A peak pulse power. An important characteristic of this diode is that it has a low capacitance which means it is not affected by high-speed signals, allowing signals to pass through without distortion. It also has a rugged construction and is able to operate at high temperatures, up to 150°C. Additionally, since the 15KP40A is RoHS compliant, it meets the standards of hazardous substances in electronic equipment.

To summarise, the 15KP40A is a widely used TVS diode that is effective in transient suppression. It is suitable for use in vehicles, high-end consumer electronics, networking equipment, industrial electronics, and automotive systems. It has a breakdown voltage of 15V, a peak pulse power rating of 40A and peak pulse current rating of 18A. It has a low capacitance line allowing high-speed signals to pass through without distortion and is designed to operate at high temperatures, up to 150°C. It is also RoHS compliant, thereby meeting all the standards of hazardous substances in electronic equipment.
