TVS - Diodes

TVS - Diodes are a kind of semiconductor diode device designed to protect vulnerable electronics from damage caused by transient voltages and currents. The P4KE110CAHE3/54 is a part of this family which is tailored to best suit in applications that need robust and efficient surge and transient overload protection. Given the present global and regional challenges posed by voltage surges, this device is increasingly becoming integral to protecting electronic circuits from burns and other damages caused by these powerful but transient surges.

Application Field

The P4KE110CAHE3/54 TVS Diode is designed for a broad range of electronic protection applications. It is capable of protecting components from voltage and current transients that can be caused by electrostatic discharge (ESD) from human contact, spikes caused by switch-mode power supplies, electro-magnetic interference (EMI) from other nearby electronic components, and lighting strikes. The P4KE110CAHE3/54 is typically used to guard sensitive equipment and components in consumer electronics, automotive systems, industrial and military systems, and data centers, which require surge protection of up to 140 Volts. It features a peak surge clamping voltage of 330 Volts and a peak surge current of 150 A. It offers low capacitance values for different devices with high-speed protection for data line interface.

Working Principle

To understand the working principle of the P4KE110CAHE3/54, one may refer to the basic working principle of a TVS diode. TVS diodes build a potential barrier, which protects electronics from voltage surges caused by external components and environmental factors. The P4KE110CAHE3/54 is a TVS diode with a low-capacitance configuration, which means that it has a reduced capacitance that is perfect for applications that require high-speed data transmission. It can conduct current far greater than its own rated currents without overheating, and has fast response time because of its small size.The P4KE110CAHE3/54 works in a very distinctive way. It enables low capacitance shield that works as a barrier between two terminals. During an abnormal surge, the diode activates the short circuit protection. Here the low capacitance shield ensures that the current will not cross it, thus protecting the device.The device is integrated on a PCB and it is connected to the power, rectifying diodes, and fuse – the latter is necessary to protect against over-current. When a surge is detected, it will activate the short circuit, protecting the device from any surge or transient.

Conclusion

The P4KE110CAHE3/54 TVS Diode is a versatile, low capacitance surge protection device that effectively shields electronic components from damage caused by voltage and current transients. It offers high surge current of 150 Amps with a peak surge clamping voltage of 330 Volts and is suitable for use across a broad range of applications, from data centers and consumer electronics to the automotive and military sectors. Its low capacitance construction and fast response time makes the device ideal for applications that require high-speed data transfer, and it is also durable enough to continue working after several activations, making it an economical option for operations.
