The ESDSR70 is a unidirectional dual-channel ESD protection diode designed to protect high-voltage data lines. The device supports a reverse working voltage of 70V and a reverse breakdown voltage of 85V, ensuring independent and stable operation of dual-channel signals under harsh working conditions. Its reverse leakage current is as low as 5μA maximum at VRWM. Under transient voltage shock, the device achieves a clamping voltage of 10V in an 8/20μs pulse test, which can effectively guide transient currents and provide precise overvoltage control for dual channels.
It fully complies with the IEC 61000-4-2 international standard, and the contact discharge and air discharge protection levels are both ±30kV. The 5pF diode capacitance helps optimize the transmission quality and electromagnetic compatibility of high-speed signals. It is suitable for industrial equipment, communication systems, and other occasions that require integrated multi-channel protection solutions with strict requirements for high voltage protection and signal integrity. The ESDSR70 adopts the industry-standard SOT-143 package.
