The Transient Voltage Suppressors (TVSs) are a class of semiconductor-based components that offer bidirectional unidirectional protection for circuits from extreme electrical transients created by electrostatic discharge (ESD), lightning, and other events. This article focuses on 15KPA22A-B application field and working principle.

The 15KPA22A-B is a bi-directional TVS Diode with an Operating Stand-Off Voltage of 15V and a peak Pulse Power Rating of 430W (8/20µs waveform). It features an ultra-low capacitance of 70pF maximum and built-in electrostatic discharge protection with a low IEC61000-4-2 ESD Clamping Voltage of 16.1V.

The 15KPA22A-B is mainly used for over-voltage protection and ESD protection in various automotive, consumer, and industrial applications, such as bus communication, onboard computer, LED Display, etc. The low capacitance is designed for signal line protection while the ESD protection is designed to prevent damage due to handling and connection in the field.

The 15KPA22A-B works by clamping the voltage levels within the TVS diode. When an excessive voltage is applied across the TVS diode, its built-in avalanche breakdown occurs, and the diode channels the voltage to the ground and thus preventing it from damaging the rest of the circuit. As a result, it helps in protecting equipment from lightning and other voltage surge events.

To summarize, the 15KPA22A-B is a bi-directional TVS diode with an Operating Stand-Off Voltage of 15V and a peak Pulse Power Rating of 430W (8/20µs waveform). The ultra-low capacitance of 70pF maximum with built-in electrostatic discharge protection and low IEC61000-4-2 ESD Clamping Voltage. It is mainly used for over-voltage and ESD protection in various automotive, consumer, and industrial applications. It works by clamping the voltage levels within the TVS diode, thus preventing it from damaging the rest of the circuit.
