TVS (Transient Voltage Suppression) Diodes are semiconductor components that are designed to provide protection against electrical surges such as ESD, EFT, and lightning strikes. They are designed to be connected in series on either side of a circuit, and when a voltage surge occurs, they limit the voltage that flows through the circuit.The 1.5KE43A is a TVS Diode designed to protect circuits from transient voltage events. It is capable of handling load currents up to 400A and withstands repetitive peak pulse currents up to 1.5kA. Its working voltage range is from 43Volts to 58Volts, and it has a capacitance of 40pF ±3%. This diode is RoHS compliant and has an operating temperature range from -55°C to 150°C.The 1.5KKE43A is most commonly used in automotive applications to provide ESD and EFT protection. It is especially well-suited for ICs that are exposed to ESD currents and other voltage events. It can also be used in industrial applications such as surge protectors, data lines, and automotive electronics. It is also used for energy storage devices such as supercapacitors and batteries.The 1.5KKE43A diode works by absorbing the energy from the voltage surge and dissipating it as heat. By diverting the surge current away from the protected circuit, it prevents the sensitive components from experiencing voltage that is higher than the specified operating voltage range. The diode also clamps the voltage to prevent further voltage spikes.In summary, 1.5KKE43A TVS diode is an ideal solution for providing overvoltage and ESD protection to sensitive electronic components, especially in automotive applications. It is capable of handling repetitive peak pulse currents of up to 1.5KAmps and has a wide operating temperature range. It can easily be implemented in any system, as it has a compact form factor and is RoHS compliant.
