TVS diodes play an important role in protecting sensitive electronics from voltage transients, which may cause damage or malfunctioning. The 1.5KE220AHE3_A/D is one of the most widely used transient voltage suppressors (TVS) that can absorb and dissipate high amounts of surge energy. This Application Note provides a brief overview of the 1.5KE220AHE3_A/D and its application fields.

Application Fields:

The 1.5KE220AHE3_A/D can be used in a variety of application fields, such as automotive, medical, industrial, communications and consumer electronics. The device is particularly well-suited for sensitive consumer electronics, given its high peak pulse power and pulse waveform performance.

The 1.5KE220AHE3_A/D is designed to provide protection against electrical transients such as electrostatic discharge (ESD), lightning, or other sudden voltage spikes. It can be used in a variety of applications, including in-circuit protection on logic or communication systems, power line protection in DC/DC converters, and protection in automotive electronics where ESD and other surges are prevalent.

Working Principle:

The 1.5KE220AHE3_A/D working principle relies on its ability to react quickly and clamp the transient voltage before it reaches damaging levels. When exposed to a sudden overvoltage event, the device switches on and its internal structure creates an opposing force, effectively shorting the line and dissipating the surge. This process, known as clamping, reduces or eliminates the surge in a fraction of time.

The 1.5KE220AHE3_A/D utilizes Zener diodes to provide its protection. Zener diodes operate like normal PN-junction diodes, containing a reverse breakdown voltage at which the diode is switched on. When this reverse breakdown voltage is reached, the diode starts to conduct, allowing all current to flow through the diode instead of the circuit.

The 1.5KE220AHE3_A/D has a low capacitance and fast response time. It not only responds quickly to an overvoltage event, but also provides a much lower working voltage than other TVS devices, enabling it to protect sensitive circuits. The device can be used in both AC and DC applications, making it highly versatile.

Conclusion:

The 1.5KE220AHE3_A/D provides a reliable and efficient way to protect sensitive equipment from overvoltage events. Its fast responding capability, low capacitance and low working voltage make it an ideal for numerous application fields, such as automotive, medical, industrial, communications and consumer electronics. To conclude, TVS diodes are essential components for any system that needs to be protected from voltage transients and the 1.5KE220AHE3_A/D offers an excellent solution.
