TVS (Transient Voltage Suppressors) diodes are semiconductor devices used for protecting sensitive electronics from transient overvoltage events in a wide variety of electrical and electronic systems. The 1V5KE400CA is a 400 watt Zener diode that provides electrostatic discharge (ESD) protection for automotive, computer, telecom, and industrial applications.The 1V5KE400CA has a low-capacitance reverse-transient clamping voltage of 400 watts, with a 2.0pF typical dynamic capacitance. It is capable of protecting against multiple line transients up to 400 Watts, including external electrostatic discharge (ESD) events. The device is constructed with a silicon junction using a Zener barrier diode technology and is designed to meet IEC ESD Standards.The working principle of the 1V5KE400CA is based on its low-capacitance structure. When a line or load transient occurs, a charge signal is generated on the device and the excess energy is dissipated. The device\'s capacitance acts as a buffer and absorbs the energy, while providing electrostatic protection. Once the energy has been completely dissipated, the device returns to its normal operating state.The 1V5KE400CA is commonly used in a wide variety of automotive, computer, telecom, and industrial applications. In the automotive industry, the 1V5KE400CA is used in a variety of safety systems, such as airbag sensors, spark plugs, and airbag crash sensors. It is also used in many computer related applications, such as USB ports, Ethernet ports, and other network components. In the telecom industry, the 1VK5E400CA is widely used in cellular base stations and routers. Lastly, in industrial applications, the 1V5KE400CA is used in a variety of power supply systems, such as UPS systems and switchgear.In conclusion, the 1V5KE400CA Zener diode provides electrostatic discharge protection for a range of applications, from automotive to industrial. Its low-capacitance reverse-transient clamping voltage of 400 watts make it ideal for protecting electrical and electronic systems from transient overvoltage events. Additionally, the device is designed and constructed to meet IEC ESD Standards, providing users with maximum protection against potential damage.
