TVS (Transient Voltage Suppressor) diodes, also referred to as surge suppressor diodes, are a type of semiconductor device. They are designed specifically to protect sensitive electronic circuits from transients (electrical surges) that can exceed normal operational voltage levels. The P4KA16AHE3/73 is one type of TVS diode designed to specifically protect automotive electronic systems.The P4KA16AHE3/73 is a shunt-mode diode array with two independent channels. The device is designed for reverse-biased applications in order to protect against electrostatic discharge (ESD), electrical overstress (EOS), and transients caused by inductive load switching. The breakdown voltage of each channel is 420VDC maximum with the rated clamping voltage going up to 16.2V peak. The device is hermetically sealed to provide a steam leak-proof environment for sensitive automotive electronics.In operation, the P4KA16AHE3/73 functions as a protective barrier against transients caused by electrostatic discharge, electrical overstress, and inductive load switching. When a voltage surpasses the diode’s rating, current passes through the diode, and the voltage is clamped to the diode’s specified breakdown voltage. This decreases the detected voltage and prevents circuits connected to the diode from experiencing intrusive voltage spikes.The P4KA16AHE3/73 is a popular choice for automotive uses, such as anti-lock braking systems, vehicle security systems, and TPMS (tire pressure monitoring systems). Because of its low capacitance and very high surge current capability, it is ideal for protecting electronic systems from damage that can be caused by voltage transients.The P4KA16AHE3/73 is also commonly used to protect industrial machinery controllers and motors from voltage transients. Factory automation and process control systems often rely on sensitive and expensive electronic components, which require protection from voltage transients. The P4KA16AHE3/73 is well-suited to these applications, because of its high peak pulse current ratings and fast response times.The P4KA16AHE3/73 is a popular device for protecting sensitive electronic components in automotive and industrial applications. It is designed to clamp the voltage from transients, providing a protective barrier for connected circuits. Its low capacitance and very high surge capacity make it an ideal choice for protecting electronics from voltage transients.
