TVS – Diodes are common types of unidirectional semiconductor devices, which are used for the protection of sensitive electronic components from excessive field or current. P4KE440C-G is an advanced TVS Diode with various applications in wireless communication systems, industrial control and IC protection. P4KE440C-G is an axial-leaded, silicon-based diode with a surge power rating of 400W, which means it is able to prevent failure of sensitive components of the circuit due to excessively high current.

The working principle of P4KE440C-G is based on the fact that when the input to the rigid circuit exceeds its rated current and voltage ratings, the conduction level of the circuit increases drastically. This large change in the conduction current is greater than that of the P4KE440C-G diode, meaning that the volt-ampere characteristic curve shows that the diode will be \'activated\' at the exact point of over-voltage or over-current. As a result, the P4KE440C-G will clamp the voltage or current down to the desired level.

The P4KE440C-G diode can be applied in a variety of fields to protect sensitive electronic equipment from surges and voltage spikes. It can be used in wireless communications systems, where the protection of the ICs from over-voltage and over-current is needed. The P4KE440C-G is also often used in industrial control systems or automotive applications, where the protection of expensive ICs from high voltage or current is important. The P4KE440C-G is capable of limiting the current to 400W peak pulse power per pulse, meaning it can protect sensitive devices from over-voltage or over-current.

The P4KE440C-G can be used in many applications due to its low capacitance, low power dissipation, low stress on the gate oxide and improved ESD robustness. By using this diode, manufacturers can protect their products from surge transients, which can lead to equipment downtime and system failure. Moreover, the P4KE440C-G can provide enhanced ESD protection for sensitive ICs, reducing downtime and service cost and providing an economical solution to the user.

In summary, the P4KE440C-G is a TVS Diode with a variety of application fields. It works by clamping high voltages or current down to the desired level when an input in a rigid circuit exceeds its rated current and voltage ratings. It has a peak pulse power rating of 400W and is often used in wireless communications systems, industrial control systems and automotive applications. It is a low component cost solution which provides an efficient and reliable protection against voltage and current surges.
