TVS (Transient Voltage Suppressor) diodes are devices that help protect vulnerable electrical components from high voltage surges. The 15KPA28-B is one of many different kinds of TVS diodes available on the market today. This section will discuss the application field and working principle of the 15KPA28-B.

Application Field

The 15KPA28-B is most suitable for general purpose overvoltage and pulse current protection. The device provides a low operating voltage of 5.5V with a minimum breakdown voltage of 28V, making it particularly suitable for DC applications in both consumer and industrial electronics. It is capable of limiting and suppressing surges up to 30A and 15kB/s, and can withstand multiple surges of high current pulses without damage. It is often used to protect circuitry from electrostatic discharge (ESD) and transient voltage spikes.

Working Principle

The 15KPA28-B works by dissipating critical voltage and excess energy through two processes: avalanche breakdown and clamping. When the applied voltage exceeds the breakdown voltage, a sharp increase in current occurs. This is known as avalanche breakdown and is the basis for the 15KPA28-B’s protection from overvoltage surges. During a clamping event, the 15KPA28-B increases its current, reducing the voltage at the protective node. This is known as the “clamping effect”, where the diode provides a high level of voltage division and current protection. The combination of these effects lead to a very effective form of surge protection.

Conclusion

The 15KPA28-B is a transient voltage suppressor diode that is used to protect against overvoltages and high current pulses. It is often used in DC applications and can withstand multiple high current pulses without damage. By dissipating excess energy through two processes: avalanche breakdown and clamping, the 15KPA28-B provides effective protection from surges.
