TVS - Diodes are components that are used in a variety of applications for the protection of analogue, digital and power electronics. The P4SMA30CAHE3/5A is one of the many solutions for such applications, offering superior surge capability and EMI/RFI protection.

Application Field

The P4SMA30CAHE3/5A is mainly designed for a wide range of devices and systems including circuit board assemblies, back plane testing, transformer protection, security systems, radar transponder, satellite communications, portable medical equipment, aerospace systems, power supplies, high power amplifiers and computers. It is particularly suitable for applications with high-voltage transients that require an increase in holding voltage due to the superior surge capabilities.

Working Principle

The P4SMA30CAHE3/5A TVS - Diode uses a unique and highly effective suppression technique that is capable of providing superior ESD suppression. The device is composed of two layers that are closely matched in both capacitance and resistance. When a high voltage transient (or Surge) is applied to the device, both the resistance and capacitance are very quickly increased due to the device\'s design. This means that the transient is quickly absorbed by the device and the EMI/RFI generated by the transient is effectively minimized.

When the transient has passed, the device is designed to return to its original resistive and capacitive values. This ensures that the original signal sent to the device is not affected by the transient. The device is also designed to be self-biased to ensure the highest suppression of EMI/RFI throughout its working life.

The P4SMA30CAHE3/5A is also designed to provide superior protection from over-voltage transients. This protection can be provided up to the highest working voltage of the device. This means that even in the event of a surge that is above the working voltage of the device, the device will be able to provide excellent protection and keep the protected device from harm.

The P4SMA30CAHE3/5A is an ideal device for applications where high-voltage transients are a concern, and offers superior protection from EMI/RFI. It is an extremely robust and reliable device that can withstand a large amount of over-voltage transients without damaging the protected devices. The device is also designed to have a low capacitance and resistance, which ensures that the signal is not affected by the application of the device. The device is suitable for a wide range of applications, and provides superior protection from EMI/RFI and over-voltage transients.
