15KPA200CATR

TVS (Transient Voltage Suppressor) diodes are an integral part of any electronic circuit protection system. They are used to provide fast-acting overvoltage protection in applications such as commercial electronic control systems, power supplies, and consumer electronic devices. A TVS diode is essentially a specialized Zener diode with either a unidirectional or bidirectional characteristic that is optimized to respond fast to surge protection. The 15KPA200CATR diode is a unidirectional device optimized for use in applications such as motor protection, overvoltage protection, and equipment control.

The purpose of the 15KPA200CATR diode is to protect sensitive electronic components from excess voltage. When the input voltage from a circuit exceeds the clamp voltage of the diode, a current surge is generated, which can damage the internal components of an electronic device. By inserting a 15KPA200CATR diode between the power source and the components, any excessive current surge is diverted through the diode, thus preventing any damage. Furthermore, the diode also provides ESD protection from electrostatic discharge.

As a unidirectional device, the 15KPA200CATR diode boasts an on-state voltage of 1.3V and can withstand a peak power of 600W. The rated reverse breakdown voltage for the device is 158V, with a maximum clamping voltage of 200V. The device features a high operating temperature range of -55°C to +175°C, and has an impressive surge current rating of 15A.

The 15KPA200CATR diode has a broad range of applications, from consumer electronic devices to medical equipment and industrial equipment control. In consumer electronics, the diode is most commonly used to protect audio and video equipment from overvoltage, while in motor protection applications, the diode prevents motors from stalling when subjected to excess electrical current. The diode is also used in sensitive medical diagnostic equipment, where it ensures accurate readings are obtained in the presence of ESD pulses or voltage transients.

As the 15KPA200CATR diode is highly sensitive to surge voltage patterns, it is important that the device’s working principle is understood before it is installed in any application. To understand the working principle of a TVS diode, it is helpful to think of it as a two-terminal electronic component that acts like a short when subjected to a surge current. The diode functions as a valve that is closed until it reaches its breakdown voltage, at which point it acts as a conductor.

When a voltage surge occurs in the circuit, electrons start to flow through the diode and the device is subjected to a large surge current. As the electrons move through the diode, the device’s resistance decreases, allowing the current to pass. The current is directed away from the sensitive components and is dissipated as heat. Once the surge is over, the diode’s resistance increases, preventing any further current flow.

The 15KPA200CATR diode is an invaluable component of any application requiring protection from surge current and voltage transients. Its unidirectional design makes it suitable for applications where reverse voltage protection is required, while its high surge current rating ensures it can provide reliable protection even under extreme conditions. Furthermore, its high operating temperature range and long life make it an ideal choice for medical and commercial applications.
