Low dynamic resistance

The TVS diode (ESD protection diode) is connected in parallel to the signal line, the power supply line, and the GND line in order to protect the circuits in the subsequent stages. The applied ESD flows through the TVS diode to the GND line. However, since the TVS diode has its own resistive component (dynamic resistance), if this resistive component is large, the ESD will not flow easily. The lower the dynamic resistance, the easier it is to absorb ESD.

The Lowlow-capacitance TVS-diode DF2BxM5 series (EAP-V)・DF2BxM4 series (EAP-IV)) has reduced dynamic resistances compared to with the conventional DF2BxM2 series (EAP-II). This increases the absorption performance of ESD and also reduces the clamping voltage, thereby improving the protection performance of electronic equipment.
