TVS - Diodes are an important component of any electronic device. They play a crucial role in protecting against spikes in power, such as when a device is hit by a lightning strike. The 1.5KE68A-T is a type of transient voltage suppression (TVS) diode, which is designed to protect against overvoltage conditions. In this article, we will discuss the 1.5KE68A-T application field and working principle.

1.5KE68A-T Application Field

The 1.5KE68A-T is a bidirectional TVS diode, meaning it is able to handle voltage in either direction. It is mainly used in communication and other IT equipment. Specific application areas include the protection of high power lines, such as those found in telecommunication networks, set top boxes, and cellular base stations. It is also used in computer peripherals, like hard drives, printers, and other peripherals.

The 1.5KE68A-T has an outstanding surge capability of 68A (8x20 μs impulse), making it an important part of protecting against any type of surge that may come from power hits or line noise. That is why it is often used to protect high power electronics from harmful electrical surges. It is also effective in protecting against forms of transient overvoltages caused by mixing different voltage levels, such as 3.3V and 5V.

1.5KE68A-T Working Principle

The 1.5KE68A-T is a surface mount diode, which means it needs to be mounted on the board in order to work properly. It is triggered by an overvoltage condition, like a lightning strike or power spike. When this happens the diode limits the voltage to a safe level, protecting the device from any damage or malfunction. It operates by clamping the voltage at a lower level than it would have been without the diode. This is done by rapidly conducting current if a voltage exceeding the maximum working voltage is applied to the diode.

The diode works by absorbing excess voltage and then slowing dissipating it until it gets back to the original voltage. This process occurs rapidly and the diode recovers after the surge is gone. This protection and recovery process is rapid due to the low capacitance. The 1.5KE68A-T does not require external components, which is an additional advantage.

The 1.5KE68A-T is a highly reliable diode, with an excellent surge performance. It has a variety of benefits, such as lower power consumption, low leakage current, and low forward voltage drop. The diode also has a good thermal stability range, from -55°C to +125°C.

Conclusion

The 1.5KE68A-T is an important part of any electronic device. It is a TVS diode that is able to protect against overvoltage conditions. It is mainly used in communication and other IT equipment, and is able to protect against sudden power spikes, such as those caused by lightning strikes. The diode also has a number of advantages, such as low power consumption, low leakage current, and low forward voltage drop. Ultimately, the 1.5KE68A-T is a reliable and effective diode that can help protect against sudden surges in power.
