15KPA18

TVS (Transient Voltage Suppressors) diodes are an important group of electronic components used in automotive, industrial and aerospace applications.

TVS diodes are basically zener or avalanche diodes designed to protect circuits and equipment from transient voltage spikes or electrical overstress (EOS). When an electrical voltage spike or surge occurs, TVS diodes help prevent damaging currents from passing through the circuit.

The 15KPA18 is an example of a type of TVS diode. It is designed to protect reliable operations in contactors, security and professional audio systems, and other applications that require protection from high-voltage spikes. The device is available in a variety of voltage and power ratings.

Application Field and Working Principle: The 15KPA18 TVS diode can be used to effectively protect contactors, security and professional audio systems, and other sensitive electronic components from lightning surges, electrostatic discharges, and other high-voltage pulses. The device can also be used to protect signal amplifier circuits from excessive voltage changes.

The device’s working principle is fairly simple. When a voltage spike or electrostatic discharge occurs, the diode’s p-n junction is quickly forward biased, allowing the device to conduct large current flow and absorb the energy from the voltage spike. The device then quickly and safely dissipates the excess energy as heat.

The device also features very fast response times - typically in the order of nanoseconds - ensuring that the protected circuit will not be damaged or disabled by the voltage spike. The device also has high surge-current ratings – up to 800V – providing a reliable level of protection for sensitive circuits.

The 15KPA18TVS diode is also highly reliable, with a power rating of up to 18 watts. This means that it is capable of protecting even the most sensitive circuits and components from damaging voltage surges and spikes. The 15KPA18 also features a wide operating temperature range – up to 105°C – making it suitable for many automotive and industrial applications.

Overall, the 15KPA18TVS diode is a reliable and efficient device that is ideal for protecting sensitive circuits and equipment from damaging electrical overstress and voltage spikes.
