SP4044 Series TVS Diode Arrays protect sensitive electronics from destructive electrostatic discharges (ESD) and lightning-induced surge events. Low capacitance diodes are integrated with an additional zener diode to protect each I/O pin against ESD and high surge events. These robust devices offer a benchmark-setting surge protection/capacitance ratio; safely absorbing up to 24A of lightning-induced surges while presenting only 1.5pF per I/O-to-Ground connection. This helps to assure minimal signal degradation. The array can also handle a minimum of ±30kV ESD, so electronics manufacturers can provide greater protection and enhance product reliability in the field.
