TVS (transient voltage suppressor) diodes are widely used in the electronics industry for protecting electrical and electronic equipment from destructive over-voltage transients. The 1.5KE170A is an important TVS diode and has a wide range of applications. This article will discuss its application field and working principle.

The 1.5KE170A is a high-speed power TVS diode with an unidirectional feature set specifically designed to protect sensitive electronic interfaces from electrical overstress conditions. The diode has an operating voltage of up to 170 V and is designed to protect against transient voltage surges up to 20 Vrms. Its small size and unique package make it ideal for space-constrained applications. It is also compliant with the international standards for ESD and EFT.

The 1.5KE170A is commonly used in power supplies, automotive electronics, industrial electronics, and portable electronics systems. It is used in many areas where over-voltage protection is required, such as computer interfaces, power supplies, and microprocessors. In addition, the 1.5KE170A is also used in DC power line protection, telecommunications, and networks.

The 1.5KE170A works by clamping voltage spikes down to an acceptable level or diverting the over-voltage to a ground or dissipating line. The device has a special power junction structure that diffuses high-speed, high-voltage ESD pulses quickly and efficiently. When a transient voltage spike occurs at the protected circuit, the device immediately begins dissipating energy and carries the transient voltage to a safe level.

The 1.5KE170A also features a low capacitance, low clamping voltage, and low leakage current. This helps reduce signal reflections and increases the overall system reliability. In addition, the device has a fast response time, which minimizes the risk of equipment damage from electrical overstress conditions.

In summary, the 1.5KE170A is an important TVS diode that is widely used in many applications for protecting sensitive electronic interfaces from electrical overstress conditions. The device works by clamping and diverting voltage spikes, and its low capacitanceand fast response time helps ensure system reliability. Overall, the 1.5KE170A is a valuable device for many applications, and provides cost-effective protection against electrical overstress conditions.
