5KP10HE3/54

Transient Voltage Suppressors (TVS) - Diodes are critical components used in the protection of electric and electronic devices. They have been used extensively in electronics industry to guard against over-voltage transients generated by lightning and erroneous power supply designs. The 5KP10HE3/54 TVS-Diodes is a fast switching, low capacitance surge protection diode for downstream port protection in automotive ethernet systems and other data lines.

Application Field

The 5KP10HE3/54 is designed for 11A line protection which allows up to 10ESD 7KV lightings IEC61000-4-2 standard. It has an operating temperature of -40 to +150 °C and a fast response time. It is mainly used for line protection in automotive ethernet systems and other data lines. The low capacitance and fast response time ensures that the signal quality of the data line is not affected. It also ensures that power supply outputs are protected against over-voltage transients due to surge events.

Working Principle

The 5KP10HE3/54 is a one-way diode surge protector which works by regulating the voltage and current. It is designed with a reverse breakdown voltage of 5 kV. When the voltage across the diode exceeds the reverse breakdown voltage, the diode enters a breakdown state in which it will conduct current in the opposite direction. The reverse current will be limited by the power rating indicated on the package and will attenuate the overvoltage. The fast switching time ensures that the device is able to reduce the peak voltage to a safe level quickly.

The device is placed across the power supply lines and acts as a clamp to protect the device connected to it from overvoltage surges or transients. When transients occur, the device will absorb the energy and dissipate it as heat, thereby preventing the voltage from damaging the device.

Conclusion

The 5KP10HE3/54 is a fast switching, low capacitance surge protection diode for downstream port protection in automotive ethernet systems and other data lines. It is designed with a reverse breakdown voltage of 5 kV and can provide up to 10ESD 7KV lightings IEC61000-4-2 standard protection. It works by absorbing energy and dissipating it as heat thereby preventing the voltage from damaging the device.
