TVS (Transient Voltage Suppressors) diodes provide protection from electrical transients and surges in a variety of applications. In this article, we examine the specific application of 15KPA160CATR and the working principle behind it.

15KPA160CATR is a discrete, fragile anti-transient diode product. It is a unidirectional device, manufactured for a wide range of applications where fast over-voltage protection is needed. This TVS diode is designed to protect sensitive components from electrical transients such as lightning strikes, electrostatic discharges, input transients and power supply perturbations. It is also available in an ROHS-compliant version.

The 15KPA160CATR is designed to protect both high voltage and high frequency circuits, such as AC - DC power supplies, portable electronics, cell phone chargers, cables, etc. Its main characteristics are rated power dissipation (P=1W) and reverse power capability (P=0.1W). Its reverse breakdown voltage (BV) is 15KV and its clamping voltage (VC) is 160V.

The working principle of the 15KPA160CATR is based on a reverse breakdown mechanism. When a transient voltage that is greater than its breakdown voltage (BV) is applied across the diode, it begins to conduct in a reverse direction. This phenomenon causes the transient voltage to be reduced and clamped at a voltage level that is lower than the breakdown voltage (VC). This voltage clamping action is known as the Zener breakdown effect, in which electrons flow through the diode’s junction and the excess charge is dissipated through the diode’s body.

The 15KPA160CATR provides fast over-voltage protection, with a response time of 10 nanoseconds or less. Its fast-acting protection mechanism prevents the device from being damaged in the event of an electrical transient. It also has a low profile and low inductance, which makes it suitable for applications with high frequency harmonics. Additionally, the device can operate from -55°C to 120°C, making it suitable for a wide range of operating temperatures.

In conclusion, 15KPA160CATR is a discrete, fragile, fast-acting anti-transient diode. It is designed for a wide range of applications where electrical transients and surges need to be suppressed. It has a reverse breakdown mechanism, which reduces over-voltage and clamps transient voltage at a safe level. Additionally, it is fast-acting with a 10 nanosecond response time, has a low profile and operating temperature, and low inductance.
