1.5KE400A-E3/73 is a transient voltage suppression (TVS) diode that has been developed to protect sensitive micro-electronic equipment against voltage transients induced by inductive and capacitive load switching. It can also be used to protect against electrostatic discharges (ESD). This diode has three main application fields and a working principle that is related to each one.
Application Field 1: Transient Voltage Suppression
The 1.5KE400A-E3/73 is mainly used for transient voltage suppression. This diode has a low dynamic resistance which helps to keep the voltage spike within the permissible limits. In addition, its high “clamping” voltage ensures that it stays within the safe working range for the electronic components. This has made it popular in the market for its ability to protect sensitive electronic circuits against various types of voltage transients.Application Field 2: Capacitive Load Switching
The 1.5KE400A-E3/73 diode is also used for capacitive load switching. Its low dynamic resistance ensures that it can effectively skip the high dV/dt transients that are associated with capacitive loading. This helps to protect the equipment from malfunction due to these transients. The diode also has a high “clamping” voltage which helps to ensure that the transients stay within the safe working range of the electronic components.Application Field 3: Electrostatic Discharge
The 1.5KE400A-E3/73 diode is also used for electrostatic discharge (ESD) protection. The diode has a low breakdown voltage which helps to reduce the static charge that is generated when a human body is in contact with the diode. This also helps to protect the electronic components from being damaged due to ESD events.Working Principle
The working principle of the 1.5KE400A-E3/73 diode is as follows. When the diode is subject to a voltage transient, it acts as a "clamp" so that the voltage does not exceed the diode\'s specified breakdown voltage. This effectively helps to protect the electronic components from voltage spikes that could damage the equipment. Additionally, the diode\'s low dynamic resistance helps to keep the voltage spike within the permissible limits. Besides these, the diode\'s high “clamping” voltage ensures that it stays within the safe working range for the electronic components.In conclusion, the 1.5KE400A-E3/73 diode is a versatile and reliable TVS diode that can be used for a variety of applications, particularly for transient voltage suppression, capacitive load switching, and ESD protection. Its low dynamic resistance and high “clamping” voltage make it a reliable option for protecting sensitive electronics from various types of voltage transients.The specific data is subject to PDF, and the above content is for reference
