A varistor (also known as voltage-dependent resistor or VDR) is an electrical component used primarily for voltage protection and noise reduction. The device has two terminals that allow the flow of electricity across a wide range of voltages. The device typically uses zener diodes and thin-film resistors to achieve its effect.

VE09M00140K is the designation of a multi-layer VDR developed by a Japanese manufacturer of protection devices, Semtech Electric Corporation. This device is designed to provide protection to high-speed data operations in a variety of industries, including automotive, medical, consumer electronics, and aerospace. It is suited for use in systems where transient voltage protection is needed, due to its fast response times and low incident energy. The device is also capable of suppressing unwanted electrical noise.

The VE09M00140K is based on the varistor principle of operation, meaning that the device’s resistance will vary depending on the voltage across its terminals. The device features a metal oxide varistor (MOV) layer that acts as a voltage-dependent resistor. This layer is sandwiched between two thin-film resistor layers. When the device is exposed to an input voltage higher than its clipping voltage, the MOV layer’s resistance will increase. This results in a reduction of the current flow.

The VE09M00140K is capable of providing protection from both overvoltage and undershoot transients. It also offers the advantage of suppressing noise caused by EMI. The device is packaged in a low-profile 0805 package, making it suitable for use in a wide variety of applications.

In terms of performance, the VE09M00140K offers fast response times with low incident energy, and ensures accurate voltage protection over a wide operating temperature range. It is also UL certified and RoHS compatible. The device’s high-voltage capability and high dielectric strength make it suitable for use in automotive, medical, consumer electronics, and aerospace applications.

Overall, the VE09M00140K is an ideal varistor for use in a variety of protection applications. It offers fast response times and low incident energy, providing a reliable voltage protection solution. The device’s UL certification and RoHS compatibility make it suitable for a range of industries, and its wide operating temperature range ensures high-quality performance.
