TVS-Diodes are electrical components that are currently being used in many applications ranging from power protection in diesel engine starter systems to photovoltaic installations. BZW04P28HE3/54 is a surface mount TVS component that is predominately used in automotive and other DC motor applications as an electrical protection.This component is a bidirectional symmetrical TVS diode with a surge current capability of 54A and a voltage clamping of 28V. It is designed to have a very low clamping voltage and is designed to be able to withstand very high surge current values. The electrical characteristics of the component are such that it can dissipate very large amounts of energy from incoming inductive and capacitive electrical surges, which makes it ideal for protecting circuits from power spikes.The working principle of the BZW04P28HE3/54 is fairly simple. The component is designed to act as a short-circuited shunt resistor, which means that when an overvoltage occurs in the circuit, the device will create an inversely proportional current through its shunt resistor. This current is dissipated as heat, thereby diverting the power away from the circuit it is meant to protect. The device is designed in such a way that the shunt resistor can handle the current without causing any damage to the system.The device has a low parasitic capacitance to reduce low-frequency interference and prevent diode currents from appearing on the supply line. It also has a wide operating temperature range of -55°C to +125°C, which makes it perfect for automotive applications as it can handle the fluctuations in temperature and voltage associated with engine start-up.In applications such as electrical systems or photovoltaic systems, the BZW04P28HE3/54 helps protect against potential power surges. It is designed to protect the system by diverting the excess electrical power away from the system and dissipating it. This is particularly useful in applications where sensitive components must be protected from electrical power transients.Overall, the BZW04P28HE3/54 is a powerful and useful electrical protection component that can be used in a wide variety of applications. Its symmetrical bidirectional design and low voltage clamping make it suitable for applications where power surges are likely, and its large surge current capability and wide temperature range make it ideal for protecting automotive systems from electrical power transients.
