1.5SMC20A R7G is a type of transient voltage suppressor diode (TVS) used for protecting low-power electronic equipment against surge forces and operating over voltage. This TVS diode works like a zener diode; when transient voltage rises, the zener breaks down and therefore clamps the voltage at a safe level. The 1.5SMC20A R7G is also known as a protective device that affects the duty cycle, shortens the rise time and losses of data transmissions.

The 1.5SMC20A R7G is typically used in AC-DC converter applications, where the mains power is either a 380V, or a 230V AC single-phase. The main purpose is to protect the power supply from over-voltage caused by surges in the mains power. It can also be used in low-voltage rectifiers for power supplies, audio amplifiers, and other types of sensitive electronic circuitry. This TVS diode is able to protect against approximately 20mV of over-voltage and is suitable for use where current levels are relatively low.

The 1.5SMC20A R7G works based on the avalanche breakdown principle, which is basically an electrical breakdown of a reverse-biased PN junction. When a voltage lower than the specified breakdown voltage is applied to the diode, it allows only for a small leakage current to pass through the PN junction. When the voltage reaches the breakdown voltage, a surge of high current will pass through the diode, and the diode acts like a short circuit. The breakdown voltage of the 1.5SMC20A R7G is 13V, and the peak surge or spike voltage is 20V.

This protective device\'s ability to protect against over-voltage depends on its capacitance. When the capacitance is increased, it will require a higher voltage before it breaks down. The 1.5SMC20A R7G is designed with a capacitance of 14pF, which is suitable for low-power applications. The diode values can vary depending on the manufacturer. The 1.5SMC20A R7G is very reliable and has a long service life.

The 1.5SMC20A R7G is typically used in AC-DC converter applications, rectifiers and other applications in low-voltage circuits. It provides protection against surges caused by harmonics, lightning, and transients. It is highly recommended to use this TVS diode in circuits that require protection from voltage transients. The 1.5SMC20A R7G has a low reverse leakage current and a high breakdown voltage, making it the ideal device for low-power applications.
