The ESD12VD9 is a highly efficient unidirectional ESD protection diode designed for data lines and various I/O interface protection. The device supports 12V reverse working voltage and 13V minimum breakdown voltage, and is configured with 15pF to 20pF diode capacitance, making it suitable for medium and high-speed applications with high signal integrity requirements. In terms of transient event response, the ESD12VD9B can achieve a clamping voltage of 20V and withstand a maximum reverse peak pulse current of up to 4A. In the face of transient high-voltage shocks, it can provide stable and effective voltage suppression for connected circuits to avoid potential damage.
Its ESD protection performance meets the requirements of the IEC 61000-4-2 standard and effectively provides an electrostatic discharge path. It is suitable for consumer electronics, industrial equipment, and other applications that focus on circuit stability and transient overvoltage protection, and have strict reliability requirements. ESD12VD9B adopts the industry-standard SOD923 package.
