1.5KE300CA-TP Circuit Protection

1.5KE300CA-TP is a TVS Diode product. It is designed to protect vulnerable circuitry from overvoltage transients by using a combination of peak power dissipation and shunt capacitance. This type of diode is used in a variety of applications such as automotive, power line, telecom, and data lines.

1.5KE300CA-TP has very good bidirectional protection, making it suitable for systems where positive or negative transients may occur. It has fast response time and low capacitance, and is capable of withstanding high surges of up to 300A (8/20μs) without permanent damage. In addition, it has high surge capability and good clamping performance.

The 1.5KE300CA-TP has a breakdown voltage of 14V, which is the voltage at which the TVS diode will start to become conductive. Once the voltage reaches the breakdown voltage, the diode will effectively form a short circuit, diverting the energy to ground and protecting the system from the overvoltage.

The working principle of the 1.5KE300CA-TP is based on the avalanche breakdown effect. When an overvoltage is applied to the diode and the applied voltage exceeds the breakdown voltage, a large amount of electrons are accelerated across the depletion region, resulting in an avalanche of current. This current is dissipated by the diode, effectively limiting the overvoltage and protecting the circuit.

1.5KE300CA-TP is mainly used for overvoltage protection for automotive, telecom, power, and data circuits. Its fast response time and low capacitance make it ideal for protecting against fast-rising transients. For automotive applications, it is often used in the protection of automotive electronic control units (ECUs) and switching systems. It is also used in other automotive systems, such as automotive safety systems, ignition systems, HID lighting, and battery protection systems. Telecom applications also benefit from the protection provided by the 1.5KE300CA-TP, as it has a fast response time which can protect against impulse voltages and improve system reliability. Furthermore, this type of diode is suitable for data and power applications, as it eliminates interference from overvoltages, ensures fault protection, and improves signal integrity.

Overall, the 1.5KE300CA-TP is an excellent TVS diode which provides good overvoltage protection and is suitable for a variety of applications. It has a low capacitance, fast response time, and high surge capability. In addition, its reliable performance is further complemented by its low cost, making it an ideal choice for protecting various automotive, telecom, power, and data circuits.
