TVS-Diodes - 1.5KE91CA-E3/73 Application Field and Working PrincipleA TVS diode, also known as a Transient Voltage Suppression diode, is a type of Rectifier that is designed to protect sensitive electronics from voltage spikes. The 1.5KE91CA-E3/73 TVS diode is an ultra-fast diode that is often used to protect powering devices from overvoltage caused by lightning, power surges and electrostatic discharge (ESD).The 1.5KE91CA-E3/73 diode is an axial-leaded ultra-fast recovery diode which has a working voltage of up to 43V. The diode has a power rating of 1.5KW and a temperature range from -55°C up to 150°C. This type of diode has a low profile and take up less board space than other types of diodes.The 1.5KE91CA-E3/73 diode has a unique structure which allows it to respond quickly to voltage spikes. It works by clamping the voltage spike and dissipating the energy through a low thermal impedance path which helps to protect the powered device from damage. This protects the device from overvoltage by dissipating the energy quickly before the voltage spike can reach the device and cause any damage.The 1.5KE91CA-E3/73 diode can be used for a wide range of applications, including industrial, automotive, military, and consumer electronics. This diode is often used in automotive applications to protect onboard computers and system controllers from accidental electrical spikes or ESD. It can also be used in military applications as a protection device or as part of an anti-jamming system. The diode is also used in consumer electronics and home automation systems to protect devices from power fluctuations and overvoltage.When using the 1.5KE91CA-E3/73 diode, it is important to ensure that the power supply is properly rated and that the diode is able to handle the load applied. It is also recommended that an EMI filter be installed to further reduce the risk of overvoltage. The diode can also be used in conjunction with fuses or other protection devices in order to provide an extra layer of protection.Overall, the 1.5KE91CA-E3/73 TVS diode is a reliable and effective way to protect sensitive electronics from voltage spikes, ESD, and overvoltage. Its low profile and flexible operating range make it an ideal solution for a variety of applications, including automotive, industrial, military, and consumer electronics. The diode is easy to install and requires minimal maintenance, making it an excellent choice for protecting electronics and preventing costly repairs.
