Littelfuse SP33R6 0.2pF, 12KV TVS Diode Arrays are forward PN junction diodes fabricated in proprietary silicon technology. These Littelfuse diodes protect each I/O pin to provide a high level of protection for electronic equipment that may experience destructive electrostatic discharges (ESD). These robust diodes safely absorb repetitive ESD strikes above the maximum level specified in IEC 61000-4-2 international standard (Level 4, ±8kV contact discharge) without performance degradation. A low loading capacitance (0.2pF) also makes the SP33R6 TVS Diodes ideal for protecting high-speed signal pins.
