ESDAXLC4-1BF3 Circuit Protection

TVS (Transient Voltage Suppression) diodes, also known as voltage clamping diodes or surge protection diodes, are solid state devices designed to protect sensitive electronic components from excessive voltage surges. The ESDAXLC4-1BF3 is a TVS diode designed for high-speed transient voltage suppression in a low-capacitance surface mount package. This device is typically used for data lines and signal line protection, and is designed to protect against high voltage transients generated by ESD (electrostatic discharge) and other sources.

Application Field

The ESDAXLC4-1BF3 TVS diode is suitable for high-speed data and signal line protection in consumer electronics, industrial automation, telecom, automotive, aerospace and military applications. It has peak surge ratings of 8.5A (5/1000 μs) and 10A (8/20 μs) respectively and a maximum working voltage of 5.5V. The device is also AEC-Q101 qualified, making it suitable for use in automotive applications.

Working Principle

The ESDAXLC4-1BF3 works by limiting the voltage that can be applied to the protected circuits. When a surge or transient voltage exceeds the breakdown voltage of the diode, current is forced to flow through the diode, which creates a voltage drop across the diode. This voltage drop limits the voltage at the protected circuits, thus protecting them from damage.

The device is designed with a low capacitance, making it suitable for high-speed data line protection, which is essential in applications such as modems, cellular telephones, and data communication systems. The low capacitance also minimizes signal distortion. The device also has a fast response time and high pulse power rating, ensuring reliable protection against voltage surges.

The device is also designed to be RoHS compliant and halogen free, making it suitable for use in lead-free applications.

In conclusion, the ESDAXLC4-1BF3 is a reliable and robust TVS diode designed for high-speed data line protection. It has a low capacitance, fast response time, high pulse power rating, and AEC-Q101 qualification, making it suitable for a wide range of applications.
