TVS (Transient Voltage Suppressor) diodes are a type of semiconductor device that is designed to protect sensitive electronic components from voltage transients caused by lighting, electrostatic discharge, motor contact switching, etc. The 5KP26A-E3/51 is a unidirectional TVS diode, meaning it can only handle currents in one direction.

The 5KP26A-E3/51 application field is mainly used in the following cases:

• Protection of sensitive equipment against voltage transients caused by lightning or switching transients in motor vehicles;
• Protection of 6.2V to 8.2V load lines from negative transients;
• Protection of 3.3V to 5.7V load lines from positive transients;
• EMI filtering and ESD protection.

The 5KP26A-E3/51 working principle is based on the fact that when an overvoltage transient occurs on a line, the device turns on and clamps the voltage to a safe pre-determined level. It then continues to conduct for the duration of the transient and returns to its low-resistance state when the voltage on the line returns to its specified level. The device can handle peak repetitive transient voltages up to 26A at a low capacitance of approximately 5pF.

The 5KP26A-E3/51 is a low-capacitance transient voltage suppressor diode that can protect load lines operating in the voltage range of 3.3V to 8.2V. It has a peak repetitive surge rating of 26A, making it suitable for applications that require surge protection of up to 26A. The device is RoHS compliant and offers superior EMI and ESD protection.

The device is also designed to provide inline protection on load lines of high-frequency data, analog, and video circuits, making it suitable for use in automotive environments. Its very low leakage current ensures protection even in hot environments, while its high peak pulse power (300W) ensures reliable protection of the load lines. The device is widely used in automotive, industrial, consumer, and communication applications, where surge protection and ESD immunity are required.

In summary, the 5KP26A-E3/51 is a unidirectional transient voltage suppressor diode designed to protect load lines operating in the voltage range of 3.3V to 8.2V from lightning strikes, electrostatic discharge, and motor contact switching transients. The device offers superior EMI and ESD protection, along with a peak repetitive surge rating of 26A. It is suitable for automotive, industrial, consumer, and communication applications where surge protection and ESD immunity are required.
