P6KE250A-T

TVS - Diodes

TVS diode is a type of voltage-protected semiconductor device, which is mainly used to limit the transient voltage on a power supply. TVS diodes are generally used to protect circuits against sudden changes in the input voltage due to lightning or any other type of transient voltage surge. TVS diodes are generally available in one of two forms: single diode and dual diode.

P6KE250A-T Application Field and Working Principle

The P6KE250A-T is a high voltage surface mount transient voltage suppression diode. It is used for various applications such as IPC equipment, signal transmission lines, computer systems, and other DC power supply lines. This diode can be used to protect circuits from the effects of lightning-induced transients, power line transients, and AC line transients. It has a maximum peak pulse power of 120 watts. It can absorb up to 400 volts of peak pulse voltage and 6.0 Joules of energy.

The working principle of the P6KE250A-T is to absorb the transient voltage or Surge energy, clamp the voltage to minimum specified values, prevent the device from being damaged from overvoltage and let the current in the protected load to continue to flow uninterruptedly.

The device works in the following three steps. First of all, when the surge begins to rear its heads, the P6KE250A-T diode will be able to absorb and dissipate the surge energy. This is achieved by a clamped structure, which moves the contact point between the anode and cathode to the right (for positive surge) to absorb the energy. Secondly, the forward voltage is held clamped during the energy absorbtion process. Thirdly, as the energy dissipates, the voltage begins to drop and the diode conducts the current during this time, allowing it to flow safely through the load.

The P6KE250A-T diode is also capable of withstanding temperatures of up to 175°C, making it suitable for use in extreme environments. It is also capable of providing ESD protection of up to 16kV. It is a great choice for applications that require maximum transient voltage protection and reliable performance.

The P6KE250A-T TVS diode is an excellent choice for various applications that require protection from transient voltages. It offers reliable protection and can be used in extreme environments. The device has a strong clamping capability and can absorb up to 400 volts of surge energy. As such, it is a great choice for applications that require both quality and reliability.
