The ESD3V3D8B is a bidirectional single-channel ESD protection diode designed for high-precision electronic systems. The device has a maximum reverse operating peak voltage of 3.3V and a minimum reverse breakdown voltage of 4.5V to ensure signal transmission quality under rated conditions. Its reverse leakage current is strictly limited at VRWM, with a maximum value of 0.5μA. In transient voltage events, the device achieves a typical clamping voltage of 9V under 8/20μs pulse test, can channel a maximum reverse peak pulse current of 8A, and provides precise overvoltage control.
Its ESD protection performance complies with the IEC 61000-4-2 international standard, and the contact discharge and air discharge protection levels both reach the highest index of ±30kV. The 15pF junction capacitance characteristic balances high speed and protection requirements, and is suitable for scenarios such as consumer electronics, industrial control modules and high-speed data lines, providing a reliable protection solution with standard certification for sensitive circuits. ESD3V3D8B adopts the industry-standard SOD882 package.
