TVS (Transient Voltage Suppressor) Diodes, are a class of devices used to protect sensitive electronic components from extreme voltage events. They are designed to clamp the voltage at the specific level, either within the range of -15kV to +15kV or via an additional terminal that further restricts the voltage to a specified level. The 15KPA100AE3/TR13 is a product from STMicroelectronics that provides TVS diode protection for high-speed signal lines.

The 15KPA100AE3/TR13 is an 11-lead surface-mount device, designed to protect sensitive equipment from high-amplitude electrical transients and overvoltage. It consists of three TVS diodes, two capacitors and an internal ESD protection diode. The 15kVpk ESD pulses are protected in each I/O pin, while the high-side input protection can withstand pulses up to 15kV. Also, the 15KPA100AE3/TR13 features overshoot clamping, suppression of conducted EOS (electrical over-stress) hazards, and a low capacitance of less than 0.25pF.

The 15KPA100AE3/TR13’s application fields include protection of high-speed differential signal lines in computer and telecom systems, as well as the protection of data ports on consumer electronics such as HDDs (Hard DiskDrives), SSDs (Solid State Drives), and media cards. It also has applications in automotive, medical, and industrial systems.

The 15KPA100AE3/TR13 works according to the principle of transient protection. The device is made up of a series of diodes and capacitors that limit the voltage especially to protect sensitive equipment against electrostatic discharges (ESD) and other electrical transients. When a voltage higher than the maximum rating of the device is introduced into the circuitry, the TVS diodes are activated and limit the voltage to a predefined level. This prevents damage to electronic components. Additionally, the capacitors are used to absorb the energy from the transient event and help bring the voltage back down to the desired level.

In conclusion, the 15KPA100AE3/TR13 is designed to protect sensitive equipment from high-amplitude electrical transients and overvoltage. The device consists of three TVS diodes, two capacitors and an internal ESD protection diode. With its low capacitance of less than 0.25pF, the 15KPA100AE3/TR13 offers excellent protection and is suitable for various application fields, such as protecting high-speed differential signal lines, data ports on consumer electronics, automotive, and medical systems.
