ABOUT ESD diodes

VRWM: Reverse cut-off voltage, in simple terms, is the maximum operating voltage allowed by the ESD. At this voltage, the ESD is in the cut-off state, and the leakage current of the ESD is very small, at a few microamps or even lower.

• VBR: Breakdown voltage, which is the voltage at which ESD starts to operate (avalanche breakdown), usually measured at a specified current, usually at a current of 1mA.

IR: Reverse leakage current, which is the leakage current measured by applying VRWM voltage to both ends of the ESD device.

IPP: Peak pulse current, usually 8/20 μ Waveform measurement of s.

VC: Clamp voltage, measure the voltage at both ends of the ESD under a given size of IPP. The VC of most ESD products is directly proportional to VBR and IPP.

C J: Junction capacitance, the junction capacitance of ESD is related to the chip area and operating voltage of ESD. For ESD products with the same voltage, the larger the chip area, the larger the junction capacitance; For ESD with the same chip area, the higher the operating voltage, the lower the junction capacitance.
