The ESD3V3D9B is a bidirectional ESD protection diode designed to provide excellent protection for sensitive data lines and various I/O interfaces. The device supports 3.3V reverse working voltage and 4V minimum breakdown voltage, and is configured with 15pF diode capacitance, which is suitable for high-speed applications requiring signal integrity.
In terms of transient event response, the ESD3V3D9B can achieve a clamping voltage as low as 9V, while being able to withstand a maximum reverse peak pulse current of up to 8A, achieving system-level transient voltage suppression.
Its ESD protection performance meets the requirements of the IEC 61000-4-2 standard and can effectively provide an electrostatic discharge path. It is mainly used in various handheld electronic devices, consumer electronics and other key areas with strict requirements on circuit stability.
ESD3V3D9B adopts the industry-standard SOD923 package.
