ESDSR05 is a unidirectional dual-channel ESD protection diode designed to provide reliable protection for general low-voltage systems. The device supports a reverse working voltage of 5V and a reverse breakdown voltage range of 6V to 8V, ensuring independent and stable operation of dual-channel signals under various working conditions. Its reverse leakage current is as low as 1μA maximum at VRWM. Under transient voltage shock, the device achieves a clamping voltage of 10V to 12V in an 8/20μs pulse test, and can simultaneously conduct a maximum reverse peak pulse current of 3A, providing precise overvoltage control for dual channels.
Complying with the IEC 61000-4-2 international standard, the contact discharge and air discharge protection levels reach ±15kV and ±10kV respectively. The diode capacitance of 0.5pF to 1.2pF optimizes the transmission quality and electromagnetic compatibility of high-speed signals. It is widely used in portable devices, consumer electronics products and other occasions that require integrated multi-channel protection solutions with strict requirements on circuit stability. ESDSR05 adopts the industry-standard SOT-143 package.
