The 1.5KE350ARL TVS (transient voltage suppressor) is a diode device designed to protect sensitive circuitry from over-voltage transients. It is usually applied in the field of telecom, consumer electronics, and automotive as it can reduce spurious voltage spikes and switching surges in circuits. This article will discuss the application field and working principle of the 1.5KE350ARL TVS.

The 1.5KE350ARL is particularly applicable in the telecom industry as it provides protection in lines connected to data and fax modems, PBX, and telephone systems. In terms of consumer electronics, it is mainly used in personal computers, hard drives, cellular phones, and other similar mobile systems. As for automotive applications, the 1.5KE350ARL is widely used in the power line of the powertrain, lighting system, and ABS system.

In terms of its working principle, the 1.5KE350ARL is designed to protect against over-voltage transients. When an over-voltage transient happens, the 1.5KE350ARL will clamp the voltage at a preset peak saw-tooth voltage level, which is commonly referred to as the clamping voltage. The maximum clamping voltage of the 1.5KE350ARL is 350V. The breakdown voltage of the 1.5KE350ARL is typically specified at 1.5kV.

In addition to its utility in protection against over-voltage transients, the 1.5KE350ARL has a low reverse leakage current. This means that the current passing through the diode is extremely low, maintaining low levels of capacitance and impedance. This provides superior protection while also reducing power loss and interference.

The 1.5KE350ARL has a wide reverse breakdown voltage range, from 1kV to 5kV. This makes it ideal for a variety of applications, including computer systems, audio equipment, automotive circuitry, and telecom equipment. It also has a fast response time, meaning that it can protect against brief voltage transients, often within one microsecond or less.

A further notable feature of the 1.5KE350ARL is the wide operating range of temperatures. This range is typically between -55°C to +125°C, meaning that it is suitable for a range of environmental conditions. This makes it suitable for a wide range of applications, such as automotive and telecom.

In addition, the 1.5KE350ARL has excellent surge current capability, with a maximum surge current of 25A. This provides exceptional protection against over-voltage transients and gives it performance that is not easily matched by similar devices.

The 1.5KE350ARL has many advantages that make it well-suited for a variety of applications, such as telecom, consumer electronics, and automotive. It has a wide reverse breakdown voltage range, low capacitance and low impedance, fast response time, and a wide operating temperature range. It also has excellent surge current capability, enabling it to handle over-voltage transients with ease. With all these features, the 1.5KE350ARL is an excellent choice for protecting sensitive electronics.
