• Introduction

P4KE16CA-B TVS Diode is an ultra fast, low operating, and high current breakdown diode, designed for ESD protection and other transient voltage suppression applications. It functions as a clamp which absorbs the transient energy and reduces the peak voltage in the power system downwards. It is capable of discharging heavy ESD stroke currents with no damage to the devices and circuits.

• Applications

P4KE16CA-B can be used in various applications where surge protection is required. The most common use is to protect sensitive equipment from electrical transients caused by Electrostatic Discharge (ESD). It is also used to protect audio/video cables, peripheral devices, computers, telecommunications equipment, data and communication equipment from transient voltage.

• Features

P4KE16CA-B offers a variety of features that make it suitable for various applications. It has a very fast response time of less than 1ns, a familiar suffix for reliability – SOD-123, a peak surge rating of 16A, an operating voltage of 600V, a high pulse handling capability with working peak reverse voltage of 1800V, and an extremely low leakage current of 0.1uA.

• Working Principle

P4KE16CA-B operates by absorbing the transient energy and limiting the peak voltage in the power system downwards. It uses a reverse avalanche diode structure, which enables it to clamp the voltage and protect the system from surges. When the TVS diode detects a surge, it turns on and clamps the voltage to prevent it from rising further. When the surge has dissipated, the diode turns off and allows the voltage to return to its normal level.

• Conclusion

The P4KE16CA-B series of TVS diodes is an efficient solution for protecting sensitive devices from over-voltage and ESD events. They are capable of handling high surge currents with no damage to the device or system. Furthermore, they have a fast response time and a low leakage current, making them a reliable device for many surge protection applications.
