1.5KE43A-B is a TVS diode with some unique characteristics making it suitable for a wide range of applications. This article will discuss the application field and working principle of this device.

1.5KE43A-B is a bidirectional Transient Voltage Suppressor (TVS) diode. A TVSdiode is a semiconductor device that is designed to provide protection when high voltage spikes are present. These spikes can come from a variety of sources such as lightning or switching surges. It can also be used to protect sensitive electronic circuits from static discharges.

The 1.5KE43A-B is a bidirectional device, meaning it is equally effective in both polarities. It has an excellent clamping capability, with an unclamped energy of 6.5 Joules and a peak pulse power of 600 watts. It also has a high breakdown voltage of 43V and an operating reverse stand-off voltage of 25V.

The application field for the 1.5KE43A-B is quite broad. It is often used in I/O interfaces, telecommunications equipment, portable electronic devices, computers, and other related equipment. It is also suitable for automotive applications and can be used in applications where high overvoltage protection is required.

The working principle of the 1.5KE43A-B is based on the concept of surge current protection. When a voltage spike or surge occurs, the 1.5KE43A-B will resistively limit the current flow between the positive and negative terminals. It also acts as a voltage clamp, limiting the peak voltages applied to the protected devices. When the surge is over, the diode will automatically reset and allow for normal operation.

The 1.5KE43A-B is a versatile and reliable device that can provide effective protection against high voltage transients. It is suitable for a wide range of applications, such as I/O interfaces, portable devices, and automotive systems. This device is also capable of providing a high level of surge current protection, protecting sensitive electronic components from damage.
