TVS diodes provide overvoltage protection when an electrical circuit experiences voltage levels beyond its rated parameters. The 15KPA180ATR is a unidirectional, ultra-low capacitance,avalanche-rated protection device specifically designed to protect high-speed data interfaces, such as USB, HDMI, and VGA, from damage caused by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. This device is designed to meet the exacting requirements of next-generation data interfaces.

Device Description

The 15KPA180ATR is designed to protect sensitive components from damage caused by voltage transients. It is a unidirectional, high-voltage protector designed to guard against faults up to 15kV in accordance with the requirements of IEC 61000-4-2. The device features an ultra-low capacitance of only 18pF to provide reliable protection of high-speed data lines while maintaining signal integrity. It is capable of handling transient peak current ratings up to 180A and pulses with repetition rates up to 400kHz alongside superior clamping performance.

Application Field

The 15KPA180ATR has a wide range of applications, including protecting mobile phones, PDA\'s, printers, personal computers, digital cameras, consumer electronics and telecommunications equipment from voltage-related surges. It is suitable for high-speed data applications, such as USB, HDMI, and VGA, and is rated for a ±30V overvoltage threshold. The device is RoHS compliant and has a maximum operating temperature of +125°C, making it ideal for applications in harsh environmental conditions.

Working Principle

The working principle of the 15KPA180ATR is based on the principle of avalanche breakdown. The device is designed to withstand transient energies up to 15kV in accordance with the requirements of IEC 61000-4-2 standard. When exposed to a voltage spike above the breakdown voltage, the device will begin to conduct. The device will then absorb the transient energy, clamping the voltage and redirecting the current away from vulnerable components. The device is designed to limit the flow of current while the avalanche-rated structure prevents permanent damage.

Conclusion

The 15KPA180ATR is a unidirectional, ultra-low capacitance, avalanche-rated protection device designed to protect sensitive circuits from ESD, EFT, and lightning-induced transients. Its high-voltage protection capability combined with low capacitance makes it ideal for high-speed data applications. The device is capable of handling transient peak currents up to 180A while providing superior protection from electric surge events.
