TVS diodes, particularly those in the form of unidirectional transil diodes, are increasing in popularity as a protection component for valuable circuitry. The IP4340CX15/P, 135 is a great example, as it is a high-performance transient voltage suppressor (TVS) which provides superior board-level protection for consumer electronics and automotive applications. Its compact design and increased peak power capability make it an ideal solution. Let’s take a closer look at what makes the IP4340CX15/P, 135 stand out.

Application Field

The IP4340CX15/P, 135 is primarily employed as a surge suppressor, surge arrester, or surge protection component for low-capacitance electronics and lighting circuits. It is designed for use in mobile, automotive, and consumer electronics applications. It can also be used to protect against ESD (electrostatic discharge) which can occur in applications such as telecommunications, high-altitude electronics, and medical devices. The robust design of this TVS diode ensures that it can handle voltage spikes up to 15V with an ESD level of 15 kV Human Body Model (HBM).

Working Principle

The IP4340CX15/P, 135 works on the principle of a Zener diode which has a reverse breakdown voltage. It contains a two-level component in which the bottom die is connected to the anode and the top die is connected to the cathode. The TVS diode is activated when a high voltage is applied to the anode and the bottom die conducts the current through the device. This causes the voltage level to drop and the top die starts conducting current. The current that passes through the top die is then diverted or absorbed, allowing the voltage to drop to a normal level.

The IP4340CX15/P, 135 also employs a built-in clamping structure which prevents the device from over-dissipation and thermal runaway. This feature ensures that the device can handle large voltage spikes without overstressing the components. Additionally, the use of a low capacitance design helps to minimize undesirable effects such as signal delay or ringing.

Additional Features

The IP4340CX15/P, 135 benefits from a low clamping voltage which helps to further diminish the risks of overstressing components. Additionally, it offers improved surge performance over other TVS diodes, and has excellent thermal stability. This makes it an ideal choice for installations in extreme temperatures. Finally, its small form factor makes it perfect for tight-fitting applications.

Conclusion

The IP4340CX15/P, 135 is a great example of a TVS diode. Its enhanced features make it ideal for a variety of high-voltage, low-capacitance applications. The built-in clamping structure helps prevent overstressing components, and it provides extra surge handling and thermal stability. It is perfect for those looking for a high-performance, compact, and reliable solution.
