15KPA180A-HR

TVS (Transient Voltage Suppressor) diodes are semiconductor devices that protect electronic circuits against unwanted transient voltages such as electrical surges, as well as electrostatic discharges. This type of device, which is also known as a Thyristor, is commonly used in applications such as commercial power supplies, automotive, aviation, and industrial applications. The 15KPA180A-HR is a high-reliability TVS diode specifically designed to protect against high-energy transient voltages.

The 15KPA180A-HR has a low working voltage of 4.0V and a maximum surge voltage of 180V. It is also capable of providing a high degree of protection against surges with up to 15kA peak pulse current. This diode also offers an ultra-wide operating temperature range of -55°C to +125°C, which makes it suitable for use in harsh environments.

The 15KPA180A-HR can be used in a variety of applications, from consumer electronics to industrial control systems. It is often used to protect systems from damaging electrostatic discharges (ESD), which can result from a variety of sources, including the user or environment. It can also be utilized in surge protection applications, to protect electronic components, such as positive temperature coefficient (PTC) relays, from inrush current surges. Such applications require a fast responding diode due to the short duration of the surge.

The 15KPA180A-HR can also be used in automotive, aviation, and marine applications. It is capable of providing a high level of protection against inductive surges, such as those generated by motors and generators. This protection is especially important in such applications, as it can help to protect sensitive electrical systems and components.

The working principle of the 15KPA180A-HR is based on a low forward voltage drop, which enables it to protect sensitive circuits from transient voltages. In operation, the diode will conduct current only once it has reached or surpassed the specified reverse breakdown voltage, thus allowing a safe conductive path to be created for the transistor. When the voltage reaches or exceeds the specified maximum peak pulse current, the diode will then release the current, thereby protecting the circuit.

Overall, the 15KPA180A-HR is an ideal solution for protecting sensitive systems from transient voltages, ESD, and inductive surges. It is well suited for use in automotive, aviation, and industrial applications, and offers a wide operating temperature range, making it suitable for use in a variety of harsh environment applications.
