The ESD7951S is an ESD protection diode manufactured by Yenji. It is a SOD-923 Scale Outline Package with RoHS compliance that is designed to protect sensitive electronics from electrostatic discharge (ESD) damage. It has a Breakdown Voltage (BV) of 7V and a Stand-off Voltage of 5.5V. It has a low Clamping Voltage (VC) of 17V (maximum) at an IEC61000-4-2 Level 4 (+/-8kV Contact Discharge) and a Capacitance of 0.02pF (maximum). Additionally, the ESD7951S is designed to be shielded from high frequency noise, providing a fast response time and improved accuracy.
