TVS diodes have become increasingly important components in protecting electrical systems as technology has advanced. The 1.5KE10C-B is a transient voltage suppression (TVS) diode that is particularly useful in dealing with transient voltage events such as electrostatic discharges (ESDs) or lightning strikes. It has a variety of applications and has a unique structure and working principle. This article will discuss the application field and the working principle of the 1.5KE10C-B.

The 1.5KE10C-B is a two-terminal surface mount TVS diode designed to protect against the damage caused by excessive transient voltages by clamping the voltage to a safe level. It is typically used in the automotive, industrial, and telecoms industries and is particularly suitable for making high-level ESD, surge, and lightning protection circuits for space-saving board designs. It supports a wide range of voltage levels, including 5V, 12V, and 24V, providing effective protection up to 10kV contact ESD, 8/20 μs surge protection up to 15kA and Ipp up to 40A. The 1.5KE10C-B also provides an ultrafast response time of less than 1 nanosecond, eliminating the need for additional external resistor components.

The 1.5KE10C-B has a unique architecture and is constructed of a pair of back-to-back diodes. This internal architecture offers ESD and surge protection in both directions and allows the device to clamps the incoming voltage to a safe level rapidly, while withstanding higher power levels that could cause excessive heating. The operating principle of the device is fairly simple. When a voltage surge occurs, the internal junction diodes will be forward biased and establish a low voltage drop across the device. This enables the 1.5KE10C-B to effectively reduce the voltage level once it reaches the clamping voltage and protect the circuits from damage.

The 1.5KE10C-B is a versatile and cost-effective device that offers protection from a variety of transient voltage events. Its internal architecture and efficient working principle provide effective protection for a wide range of voltage levels, while eliminating the need for additional external resistor components. As technology continues to develop, the protection provided by TVS diodes become ever more crucial, and the 1.5KE10C-B is an invaluable component in ensuring the reliability and longevity of electrical systems.
