TVS - Diodes refers a series of transzorb diodes, which offer an effective protection to the circuit by clamping the voltage swings. 15KPA43A-B is one of them, widely used in automotive electronics.

15KPA43A-B is an advanced bidirectional unidirectional electrostatic discharge protection diode. It is an efficient tool to protect board-level components from voltage transients generated by ESD and other transient events. It offers excellent protection to any type of electronic circuit.

The application field of 15KPA43A-B is wide, and includes automotive controllers, system management units, audio and video systems, industrial modules, etc. It is designed to protect sensitive parts from destruction caused by ESD and other transient currents. The peak pulse current of the device can reach as high as 43A, making it ideal for industrial-level applications.

15KPA43A-B is a two-terminal (diode) component in a chip package. It is composed of two p-n junction diodes connected to the source and drain electrode, respectively. The source and drain are connected by a zener breakdown region, thus forming an ESD protection channel. During operation, when a positive voltage is applied to the input terminal, the current will flow in the positive direction. When the voltage exceeds the zener breakdown voltage, the internal breakdown diode will turn on. This will cause the current to flow in the opposite direction, thus clamping the voltage.

The working principle of the 15KPA43A-B lies in the reactance of the device. It features a high reactance to ensure a low impedance path for the ESD current, thereby limiting the current level. Furthermore, the device is capable of sustaining high peak currents for up to 10ms, providing additional protection against ESD transients.

15KPA43A-B is an excellent solution for protecting electronic circuits from ESD and other transients. With its wide application field, high performance, and long life cycle, it is an ideal choice for various types of industrial applications.
