TVS - Diodes are an important device used to protect electrical and electronic devices from high voltage transients. The 15KPA51E3/TR13 is a unidirectional TVS Diode designed to protect against surges and noise in sensing circuits. 

It consists of a pair of N-Channel, Silicon ultra-low voltage diodes connected in series to provide a high-breakdown voltage, low-capacitance unidirectional protection in sensing circuits. The 15KPA51E3/TR13 provides a low current breakdown of 50V, enabling it to protect against high voltage transients in a wide range of sensing applications. 

The 15KPA51E3/TR13 provides protection against overvoltage, ESD, EFT, and power surges. Its applications include television sets, digital cameras, portable electronic devices, automotive, and industrial equipment. The device has an IEC 61000-4-2 Level 4 ESD protection of 15KV air and 8KV contact discharge. It also has an IEC 61000-4-4 EFT protection up to 40Amps. This is in addition to its protection against transients up to 1500V and power surges up to 100 Amps, 6KV pulse width 10usec. 

The working principle of the 15KPA51E3/TR13 is based on the reverse breakdown voltage of a diode. It is usually connected to the power line of an electronic system, and when a surge or transient voltage is applied across the diode, it will reach a preset breakdown voltage and become reverse polarized. This forces the current to flow through the diode away from the protected parts of the circuit, thus providing protection. 

The 15KPA51E3/TR13 is a widely used TVS diode for the protection of sensitive electronics from power surges and noise in applications requiring the highest reliability. Its high-breakdown voltage, low-capacitance, and ESD and EFT protection characteristics make it a great choice for protecting against overvoltage, ESD, EFT, and power surges in a wide variety of sensing applications.
