TVS-Diodes: 15KPA160 Application Field and Working Principle

TVS-Diodes, also called Transient Voltage Suppressors or Transient Voltage Suppression Diodes, are semiconductor devices specifically designed to protect sensitive electronic equipment from surges and transient spikes of excessive high voltages. They are available in a range of ratings and shapes, and the 15KPA160 has become one of the more common devices for applications due to its steady-state power rating and multiple configurations.

The 15KPA160 is widely used in various applications to protect circuit components from damaging transients or to provide clamping of excessively high voltage levels. It can be utilized in HDD and power system applications such as automobiles, computers, mobile phones, network servers, and other consumer electronics. In addition, it can be applied to industrial applications including power supplies, battery chargers, lighting control systems, manufacturing machines, HVAC systems, and many more.

Let’s have a closer look at the working principle of the 15KPA160. When a transient voltage occurs, the junction of the diode begins to conduct and its anode current quickly increases. The current flows through the diode to the grounded terminal and charges a series of capacitors in parallel, forming a low-impedance path to ground. This results in the reduction of the voltage that the circuit is exposed to, preventing the circuit from failing due to high-stimulus currents.

The 15KPA160 has several advantages that make it a great fit for a variety of applications. First of all, it is able to absorb large surge currents, up to 3700A. Furthermore, it has a low and predictable clamping voltage, which is usually around 15V. This high voltage savings results in improved system reliability and a reduced downtime compared to other transient suppression devices. Additionally, the device provides a bidirectional response to reduce negative transients without self-breaking, and it can be housed in an ultra-miniature SMD package.

In conclusion, the 15KPA160 is one of the most widely-used transient voltage suppressors due to its high voltage savings and multiple configurations, making it an ideal choice for various consumer electronics and industrial applications. With its steady-state power rating, low clamping voltage and bidirectional response, the 15KPA160 is capable of providing great protection against transient surge current to ensure system reliability.
