20KPA68C-B Circuit Protection

TVS - Diodes serve to protect electronic circuits from voltage spikes and are commonly used in various applications. The 20KPA68C-B is a type of TVS diode specifically designed for applications where both a low capacitance (< 0.2 pF Typ) and a low power dissipation (< 1 W typ) are required. It offers a low operating voltage and a fast response time, all with a very wide breakdown voltage range from 63V to 70V. This makes the 20KPA68C-B suitable for a wide range of applications, from automotive to consumer and OEMs.

The 20KPA68C-B uses a two-terminal package, which allows for easy assembly and a space-saving design. Its low package capacitance ensures a low contact-to-contact capacitance and improved system performance. The device also has an unmatched combination of surge handling and operational temperature range, increasing its versatility.

In general, the purpose of the 20KPA68C-B is to act as a shield or barrier for electronic circuits. It does this by preventing high voltage transients or spikes from reaching the circuit by redirecting them to ground. When used in combination with other protection components such as an intended series or shunt inductors, the 20KPA68C-B helps to protect the circuit’s components from direct damage. Other components used include resistors, capacitors, or both.

In terms of its working principle, the 20KPA68C-B is designed to keep the voltage between two of its terminals below a predetermined value. If the voltage reaches the maximum permissible value, the device automatically activates, redirecting the voltage spike to ground. Once the voltage spike is gone, the device then switches off and behaves as an open circuit. This allows it to protect the circuit from any overvoltage conditions.

In conclusion, due to its low capacitance, low power dissipation, wide voltage range, and fast response time, the 20KPA68C-B is an ideal choice for protecting against voltage spikes. It is also versatile enough for use with various other components to provide further protection. Its two-terminal package allows for easy assembly and a space-saving design, while its working principle of limiting the voltage between two of its terminals offers a reliable and effective means of protecting against electrical overvoltage.
