TVS – Diodes are components designed to prevent undesired direct and alternating current from damaging electrical components. This is achieved by providing a path for current to -ground with minimal resistance, thus, the surge is absorbed when it is directed to the ground. TVS – Diodes come in various ratings and package sizes, some of which are the 5KP180C. The 5KP180C is designed to provide reliable protection of contemporary loads and circuitry from electrical explosions, using an optimum strip point.

The 5KP180C is a unidirectional bidirectional dual suppressor diode designed for high energy protection against voltage transients. This component is specified to withstand a maximum working voltage of 180V, meaning, it can handle voltage surges higher than this without violation. The 5KP180C has a maximum power pulse rating of 600 Watts and is available in a 5.0mm×6.0mm×1.8mm SMB package. This device provides high reliability as it is built with silicon avalanche technology and is particularly suitable for direct and alternating current transients which occur in common modem and telecoms installations.

The 5KP180C provides protection in a number of areas including, transient suppression, AC and DC line protection, power supplies, etc. Specifically, this component is suitable for use in consumer electronics such as personal computers, tablets, cell phones, and industrial automation equipment, or any other application which benefits from transient protection.

The working principle of the 5KP180C is similar to that of other TVS – Diodes; it uses an optimized clip point to suppress the voltage transients. When a surge of voltage passes through it, the avalanche breakdown of the diode produces ions which rapidly react with the electrons in the circuit. This reaction acts as a voltage clamp, rectifying the current and diverting it to the ground instead of passing it through to the circuit. This process is known as ‘avalanche breakdown’ because a high concentration of positive ions created by the electrons break through the barrier and quickly react with the negative ions. This keeps the voltage surge from damaging the delicate electronic components by limiting the transient spike to a predetermined voltage.

In conclusion, TVS – Diodes, such as the 5KP180C, provide reliable protection against voltage transients which occur in common consumer electronics and industrial automation equipment. The 5KP180C uses optimized clip point technology to quickly divert a surge of voltage to the ground, thus, preventing it from damaging circuit components. This rugged, high reliability component is designed for use in a number of applications and is available in a 5.0mm×6.0mm×1.8mm SMB package.
