TVS (Transient Voltage Suppressors) diodes, otherwise known as TransZorbs or Transil diodes are becoming an increasingly important safety feature for today’s electronics. They are widely used to protect sensitive electronic components from power surges, or transients, in electrical circuits whether they be AC or DC, and come in a variety of shapes, sizes, and ratings. One specific variation is the 15KPA24C-B TVS diode, which is a three-terminal device designed to provide protection against overvoltage transients and ESD protection.

Function of 15KPA24C-B TVS Diode

The 15KPA24C-B TVS Diode is a 24-volt transient voltage suppressor diode that offers enhanced ESD protection with low dynamic resistance. It is specifically designed for protecting sensitive electronics like microcontrollers, transistors, diodes, and LEDs during transients or ESD events. The device provides a means for shielding the circuit from high overvoltage transients and supplying a surge current to ground when an ESD event occurs.

The diode is designed to clamp transient voltage spikes up to 15KV when connected in series with the supply line. When operating normally, it presents a low impedance path to ground to allow for the flow of high surge current during an ESD event. This is achieved by breaking down the reverse voltage transient at specific breakdown voltages, thus limiting the peak voltage to a safe value that the electronic components of the device can withstand.

Application Fields of 15KPA24C-B TVS Diode

The 15KPA24C-B TVS Diode is a reliable choice for a wide range of applications where protection from ESD and overvoltage transients is required. These include but are not limited to automobiles, telecommunications, consumer electronics, industrial and medical equipment. The low leakage current and footprint size make it a suitable option for use in multiple locations and in tight spaces, making it an attractive choice for those looking to maximize protection without taking up additional space.

Working Principle of 15KPA24C-B TVS Diode

The 15KPA24C-B TVS Diode works by connecting a semiconductor junction between two electrodes, often referred to as anode and cathode. When operating normally, the diode acts as an open switch, providing an infinite resistance path between the two electrodes and preventing any current from traveling between them. However, when an overvoltage transient occurs, the diode quickly and automatically switches over to a closed connection, allowing the current to pass between the two electrodes and dissipating the overvoltage transient.

The breakdown voltage of the 15KPA24C-B TVS diode determines the voltage at which it will switch from open to closed. The current that flows between the two electrodes during this time is known as surge current, and it is proportional to the magnitude of the overvoltage. When the transient voltage has returned to normal, the diode automatically switches back to an open connection, providing a high resistance path between the two electrodes and preventing any further current from traveling between them.

Conclusion

The 15KPA24C-B TVS Diode is a reliable and effective way to protect sensitive electronic components from ESD and overvoltage transients. With a wide range of applications, low leakage current, and enhanced breakdown voltage, it is an attractive choice for those looking to maximize protection without breaking the bank or taking up extra space. By understanding the working principle of TVS diodes and the features of the 15KPA24C-B in particular, one is sure to make an informed decision when selecting the right protection for their device.
