TVS diodes are mainly used to protect circuits from high voltages of short duration. The TVS diode P6KE18CA is a unidirectional device, designed to protect voltage-sensitive components from over-voltage transients, which could damage components or cause circuit malfunctions. It is especially effective in providing protection from high energy transients from external sources such as inductive loads.

P6KE18CA application fields include consumer electronics, medical equipment, telecommunications, automotive electronics, industrial electronics, etc. For example, it can be used in electric circuits of digital phones or computers. It can be used to protect against overvoltage in cell phones, LCD TVs, DVD players, power adapters, electric toys, digital cameras, Personal Digital Assistants (PDAs), and other communications equipment.

The working principle of a TVS diode is based on the avalanche breakdown principle. When an electrical current is applied to the silicon junction of the diode, electrons move across the junction due to the current flow. When the voltage exceeds a certain threshold, called the breakdown voltage, the current suddenly increases exponentially as it is transmitted through the avalanche of electrons. This sudden and dramatic current increase is what protects the circuit from high voltages.

The P6KE18CA is a low capacitance, low clamping voltage transient voltage suppressor (TVS) diode. It has a maximum reverse leakage current of 10 mA and a maximum peak pulse power of 14000 w. It also has a very fast response time of less than 1 nanosecond to high energy transients. The P6KE18CA is suitable for applications requiring high level of protection against transients and electrical overstress.

The P6KE18CA can withstand a maximum forward surge current up to 200 amps. In addition, it has a maximum peak pulse current of 2000 amps. It has a clamping voltage of 18 volts, and its junction-to-case thermal resistance is only 0.5°C/W. This low thermal resistance is important for applications that require a high level of performance in high temperature environments. In addition, its 50 percent lead-free package ensures low-profile mounting and superior electrical performance.

The TVS diode P6KE18CA is an ideal solution for protecting sensitive electronic circuits from high voltages. Its low capacitance and fast response time make it suitable for high frequency electrical overstress protection. Its high peak pulse power handling capabilities enable it to protect vulnerable components from overvoltage transients. Additionally, its 50 percent lead-free package offers superior electrical performance and low-profile mounting options.
