TVS - Diodes are a special class of electronic components used to protect electronic equipment from excessive voltage spikes or “transients.” Transients occur during power surges that occur during storms and power outages or on power lines that undergo large voltage swings. They are also found in industrial, commercial, and consumer electronic equipment used to protect sensitive electronic components from overvoltage. P4KE220CA-TP is a popular TVS-diode device used for transient voltage protection.

The P4KE220CA-TP is a Radial Leaded 27V Transient Voltage Suppression Diode developed by Nippon Chemi-Con Corporation. It is a low-capacitance, 3-pin device suitable for ESD (Electro-Static Discharge) protection in sensitive applications such as USB, Ethernet, and high-speed signal lines. It is ideal for protection of high-speed abnormal pulse and shock overvoltage, as well as ESD overvoltage suppression.

The P4KE220CA-TP consists of a semiconductor diode biased by resistors connected in series between the cathode and anode pins. The biasing resistors limit the peak reverse voltage to the leakage current of the diode. When an overvoltage occurs, the voltage exceeds the peak reverse voltage and triggers the avalanche breakdown of the diode. This reduces the overvoltage to a safe level, protecting the sensitive components of the equipment from being damaged.

The P4KE220CA-TP is able to withstand transient voltages up to 27V, and the peak surge power manipulation capability of the device is an impressive 1500W. The suppression speed of the device is also quite fast, requiring only 2 nanoseconds for most overvoltage conditions. The low capacitive effects of the device also make it suitable for use in high frequency and high speed applications. In addition, the P4KE220CA-TP also has high surge current handling capability, offering a maximum clamping voltage of 48V @ 300A.

The P4KE220CA-TP has many applications in various electronics. It is primarily used as a ESD protection device for high speed signal lines in consumer electronics such as USB, Ethernet, and high speed signal lines. It is also used for protection of high speed abnormal pulse and shock overvoltage, as well as for protection of power supplies from voltage transients. In addition, the P4KE220CA-TP is also used in automotive and medical applications where anti-static protection is necessary.

In conclusion, the P4KE220CA-TP is a versatile and reliable TVS-diode device suitable for transient voltage protection. It is ideal for use in a wide range of applications, from consumer electronics to automotive and medical applications. It is easy to use and can withstand large amounts of transients and high surge current handling capabilities. With its fast suppression speed, low capacitive effects, and high surge power handling capabilities, the P4KE220CA-TP is a great choice for reliable TVS-diode protection.
