TVS - Diodes

A TVS (Transient Voltage Suppressor) or a diode is an electronic component that can protect circuits from potentially damaging high voltage or electrical transients. In other words, it protects the circuit from over-voltage, over-power, over-current, or short-circuit conditions. This article will discuss the application field and working principle of the 15KPA240-A-B diode.

Application Field

TVS-Diodes are used in a variety of electronic applications including computers, telecommunications equipment, automotive electronics, and consumer electronics. In particular, the 15KPA240-A-B diode is designed to protect equipment from induced electrical noise, power surges, and overvoltage conditions. It is suitable for use in high power consumption applications and can provide protection up to 150V.

Working Principle

TVS-Diodes are voltage-sensitive devices that activate when the applied voltage surpasses a certain trigger level. When the diode is triggered, it begins to conduct and divert the energy away from the circuit. The 15KPA240-A-B has a low voltage rating of 7.5V and can be triggered by voltages as low as 5V. Once the voltage surpasses the trigger level, the diode conducts and divert the energy away from the circuit, ultimately protecting it from overvoltage or electrical transients.

When the voltage returns to a safe level, the diode returns to its original non-conductive state. This process is known as clamping and is the primary mechanism of action for TVS-Diodes. The clamping voltage for the 15KPA240-A-B is 11V, meaning that it will not allow any voltage greater than 11V to pass through the circuit.

Conclusion

The 15KPA240-A-B is a TVS-Diode designed to protect circuits from high-voltage or electrical transients. It works by clamping the voltage at a predetermined level, preventing any voltage greater than that level from passing through the circuit. This diode can provide protection up to 150V and is suitable for a wide variety of electronic applications.
