TVS - Diodes are used to protect semiconductor devices from potential current and voltage damages in a wide range of applications. The A5KP210CA-G is one of such TVS - Diodes, it is a unidirectional SC-74 5.0 Volt transient voltage suppressor with high surge power rating of 210Watts at 8/20μs pulse. It is designed to protect up to 5V power and signal lines from voltage surge and ESD caused by lightning and other transient voltage events.

A5KP210CA-G Application Field

The application field of the A5KP210CA-G TVS - Diode mainly includes such fields as consumer electronic appliances, such as cell phone, digital cameras, computer peripherals, automotive electronics, hand held electronic appliances, medical electronics, LED lighting and office automation.

Particularly, for consumer electronic appliances, the A5KP210CA-G helps protect not only the power and signal lines between the PCBs, but also the internal connection of cell phone, digital cameras, computers and other electronic items. Its high surge power rating of 210Watts gives it a wide range of protection from a wide range of voltages, making it suitable for these fields.

A5KP210CA-G Working Principle

The operating principle of the A5KP210CA-G is based on a zener diode configuration with an internal controlled avalanche effect. This kind of configuration results in a low thickness, low leakage rating, higher peak pulse current rating, higher surge power rating, and a wider voltage range compared to other TVS - Diodes.

When the voltage exceeds the specified clamping level of the diode, it will enter “forward-biased” state, as the current increases the spark-over voltage is reached; this is known as avalanche breakdown and is crucial for the overvoltage protection of the protected devices. The excess current is absorbed and directed away from the connected device, thereby preventing any potential damage.

At the same time, the A5KP210CA-G also provides protection from Electrostatic Discharge (ESD), lightning surge, electrical transients and other overvoltage disturbances. It achieves ESD protection by utilizing its patented Adiabatic Turn-On Technology which ensures fast response time and high ESD protection level.

Conclusion

The A5KP210CA-G TVS - Diode is one of the most popular TVS - Diodes on the market due to its multiple field certifications, international recognitions, and high surge power rating of 210 Watts. It provides the most cost effective protection for a wide range of applications such as consumer electronics, automotive electronics, medical electronics, and LED lighting. The diode has a wide voltage range, low leakage rating, and a high peak pulse current rating, making it suitable for the toughest overvoltage protection requirements.
