The SP4203 integrates low capacitance diodes to provide electronic equipment protection from destructive electrostatic discharges (ESDs). These robust TVSs can withstand repetitive contact or air ESD discharge events at ± 30 kV levels without suffering any performance degradation. This exceeds the ESD contact and air discharge test requirements of IEC 61000-4-2. Additionally, the TVS can withstand an 8/20 surge current event as defined in IEC 61000-4-5 2nd edition up to 10A and still provide low voltage clamping levels.
