1.5KE12CATR

TVS - Diodes (Transient Voltage Suppressor Diodes) are semiconductors that protect circuits from voltage overloads and surges. They are passive components that are used to reduce the damage from electrical spikes or surges in electronic equipment. The 1.5KE12CATR is one such diode and this article will outline the application field and working principle of this diode.

Application Field of 1.5KE12CATR

The 1.5KE12CATR can be used in a variety of electronic equipment, such as cell phones, computers, motor controllers, lighting systems, and even medical equipment. The diode is useful for any device that requires protection from voltage surges. It is designed with a low capacitance and high-voltage surge rating, making it ideal for protecting sensitive electronics in environments where voltage surges are common. The 1.5KE12CATR can withstand a maximum peak pulse power rating of 12.5kW and a surge power of 2kW.

Working Principle of 1.5KE12CATR

The 1.5KE12CATR operates on the principle of avalanche breakdown. This process occurs when electrons that are traveling along a PN junction are accelerated by an applied electric field to a point where they collide with the atom in the depletion zone, creating more electrons that then speed up to cause a chain reaction. The result is a rapid flow of current, which dissipates the voltage along the PN junction.

During normal operation, the 1.5KE12CATR acts as an open circuit, allowing current to flow through it. However, when the voltage exceeds the rated value of the diode or an open circuit voltage of 12V, avalanche breakdown occurs. This results in a high-speed current flow that rapidly dissipates the voltage, thus protecting the device from further damage. The 1.5KE12CATR also has a low clamping voltage which keeps the voltage within a safe level.

Conclusion

The 1.5KE12CATR is a useful semiconductor component that can be used in a variety of electronic devices. It operates on the principle of avalanche breakdown and is useful for protecting sensitive equipment from voltage spikes and surges. It can withstand a maximum peak pulse power rating of 12.5kW and a surge power of 2kW. The 1.5KE12CATR is an ideal choice for any device that requires protection from voltage spikes and surges.
