TVS diodes can protect sensitive electronic components from electrostatic discharge and other power surges. They are also used as protection circuits for high-frequency transient voltage surges in electronic systems. A 15KPA20CA-B is a type of transient voltage suppressor (TVS) diode designed specifically for automotive applications.

15KPA20CA-B Application Field

The 15KPA20CA-B comes with an avalanche breakdown voltage of 20 volts, making it ideal for a wide range of automotive applications, such as automotive fuel injection systems, power door control systems, and spark generation in internal combustion engines. It can also provide overvoltage protection in power distribution systems, and can be used for surge protection in electronic control units.

15KPA20CA-B Working Principle

TVS diodes operate by utilising an avalanche breakdown voltage, or breakdown voltage, when very high levels of voltage begin to flow through them. This causes the diode to saturate, minimizing the surge voltage to a safe level. The 15KPA20CA-B is designed to be a bidirectional transient voltage suppressor, meaning that it provides surge protection from both positive and negative polarities.

When there is no transient voltage surge, the 15KPA20CA-B is an open circuit, not conducting any current. When a transient voltage exceeds the breakdown voltage, the 15KPA20CA-B quickly saturates, which provides protection from voltage spikes. When the excess voltage is removed, the diode returns to an open circuit state, ready to protect from any future transient voltage.

The 15KPA20CA-B is a low capacitance, low resistance, and low clamping voltage diode, making it suitable for a wide range of automotive applications. It is designed for a breakdown voltage of 20 volts, making it well-suited for 12V automotive applications. Because of its low capacitance, it also provides excellent EMI protection. The 15KPA20CA-B is a robust device, with a peak power rating of 835W and a maximum peak pulse current rating of 400A.

The 15KPA20CA-B is a great choice for automotive applications that require protection from electrostatic discharge, power surges, and other transient voltage events. It is a robust and reliable TVS diode, designed specifically for automotive applications. With its low capacitance, low resistance, and low clamping voltage, it is ideal for a wide range of automotive applications.
