TVS-Diodes are devices that are used in numerous applications that require protection from voltage transients and surges. They are typically used in high-voltage, high-current applications that typically exceed the levels of an individual diode. 15KPA150A-HR is one such device, an automotive grade TVS diode array that is often used in the automotive industry for load dump and overvoltage protection for electronic control units (ECUs).The device is a quad common-cathode TVS diode array that provides protection from transverse voltage peaks that are typically associated with automotive loads. It is an automotive rated device with a 150A (8/20µs) peak pulse current and a breakdown voltage of 15V. It also has an extended operating temperature range (-55°C to 150°C). The device is well-suited for the automotive environment, providing superior electrical characteristics with low clamping voltage and distance to its breakdown.The 15KPA150A-HR has a working principle that is based on the concept of a thyristor, which utilizes two or more electrodes, typically four, along with a control electrode for the purpose of current conduction control. When a current surge or voltage transient occurs, the thyristor turns on and becomes an electrical gate, pulling current from the circuit. This current is then discharged through the device and the transient dissipates. The 15KPA150A-HR offers high efficiency protection against high-voltage transients by controlling the gate between the two or more thyristors. The thyristors are triggered when a voltage reaches a certain level, and a certain amount of current flows, connecting the cathode and the gate electrodes. This connection then enables the forward current to flow and the transient is quickly absorbed and discharged. For applications in the automotive industry, the 15KPA150A-HR provides superior performance in the areas of load dump and overvoltage protection. It also provides an ultra-low-capacitance of 0.9pF, which prevents signal integrity problems especially in sensitive electronic circuits. This device is designed to offer superior protection in an automotive environment where temperatures can range from -55°C to 150°C.The 15KPA150A-HR is an essential component for automotive electronics and can be used in a wide range of applications such as onboard computing, headlights, airbags, fuel injection, and other automotive electronics. It is also useful for military and aerospace applications that require protection from high-energy transients.In conclusion, the 15KPA150A-HR is an automotive grade TVS diode array that can be used in numerous applications for protection from overvoltage and load dump transients. It has an extended temperature range, low clamping voltage, and an ultra-low-capacitance of 0.9pF. It is an essential component for automotive electronic systems and can also be used in military and aerospace applications.
