TVS - Diodes are commonly used to protect semiconductor devices from high-energy voltage transients, which can cause over-voltage in a circuit. The SMC5K15A-M3/H is one such device and provides surge protection in a wide range of power supply applications. It utilizes a low-capacitance, high-diode clamped structure, making it ideal for protecting delicate electronics from power surges.

The SMC5K15A-M3/H offers superior level of protection from power surges and transients, which can otherwise damage sensitive components. It is capable of withstanding transient pulses of up to 15A in the low voltage range and up to 5KW in the high voltage range. The device incorporates an advanced protection algorithm which uses both clamping and decoupling technologies to provide superior performance.

The SMC5K15A-M3/H is designed to be installed in a device\'s power supply circuit, where it acts as a protective circuit breaker. In the event of a burst of surge current, the device responds by quickly switching from its normal conducting state to a high impedance state. This prevents the surge current from reaching the vulnerable electronic components, while the dissipated energy is limited to a level that will not damage the component.

The working of SMC5K15A-M3/H can be better understood by breaking it down into two separate components; the protective circuit and the voltage protection. The protective circuit works by automatically detecting the presence of an over-voltage condition and then quickly switching the device from its normal conducting state to a high impedance state. This effectively blocks the surge current from reaching the sensitive components, protecting them from potential damage.

The voltage protection is also vital for protecting the vulnerable components from over-voltage conditions. It works by using a capacitor and diode clamping circuit to limit the voltage overshoot that occurs when a surge current attempts to flow. This helps to limit the effect the voltage overshoot has on the sensitive components of the circuit, ensuring that they will not be damaged by the surge.

The SMC5K15A-M3/H is ideal for use in applications such as power supplies, computer motherboards, telecommunications, consumer electronics, and automotive electronics. Its efficient functioning and superior protection capabilities make it an invaluable asset in protecting vulnerable electronic components from damage due to surge currents.
