P4KE7.5C-B Circuit Protection

TVS diodes are semiconductor device used to protect electronic equipment from transient overvoltages. The P4KE7.5C-B is a positive temperature coefficient (PTC) transient voltage suppressor (TVS) diode designed to protect high speed data line interference. The P4KE7.5C-B is available in an SOT-23 package.

The P4KE7.5C-B has its typical breakdown voltage rated at 7.5V. The device has a reverse stand-off voltage rated at 4.0V. This TVS diode can protect against overvoltage transients caused by inductive load switching, lightning, motor vehicles or static charges. The device provides over-current clamping protection and protects two-terminal data line from damage caused by ESD.

The P4KE7.5C-B can be used to protect against electrical transients caused by power faults. It can also be used to protect against surge induced transients on a variety of high speed data lines, such as ESD, lightning, inductive load switching, motor vehicles, etc. The TVS diode can provide a reliable protection against both common and differential mode transients.

The P4KE7.5C-B adopts the reversed stand-off voltage structure which allows for a wide reverse stand-off voltage range. The device provides a low capacitance in reverse biased, and low leakage current across the junction in a wide operating temperature range. Furthermore, the TVS diode is designed for both over-current and over-voltage protection.

The working principle of the P4KE7.5C-B is based on a Zener diode’s ability to conduct current when the applied voltage exceeds its rated breakdown voltage. When a high voltage pulse is applied, the device’s low capacitance will begin to rapidly increase and initiate an avalanche breakdown. The avalanche breakdown produces a large amount of current which is redirected away from vulnerable circuits and discharged to ground. This reduces the voltage to a safe level that can be tolerated by the system’s components.

The P4KE7.5C-B is widely used in automotive applications, consumer electronics, computer peripherals, and industrial equipment. It is used to protect against electrical transients, ESD, lightning, and inductive load switching. The device’s low leakage current, low capacitance, and wide operating temperature range makes it ideal for use in automotive, consumer electronics, computer peripherals, and industrial equipment.

In conclusion, the P4KE7.5C-B is a positive temperature coefficient transient voltage suppressor diode used to protect high speed data line interference. Its low leakage current, low capacitance, and wide operating temperature range makes it ideal for a variety of automotive, consumer electronics, computer peripherals, and industrial applications. The device provides both over-voltage and over-current protection for the system’s components.
