ESD Protection for I/O and Power Ports - SP1053/SP1054 Series

Littelfuse's SP1053 and SP1054 series designed for ESD protection

Littelfuse's unidirectional SP1053 and SP1054 series provide ESD protection for I/O and power ports in compact, hermetically sealed plastic packages. The avalanche breakdown diodes fabricated in a proprietary silicon avalanche technology 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 can safely absorb repetitive ESD strikes at ±8 kV and ±30 kV (contact discharge, IEC 61000-4-2) without performance degradation. Additionally, each diode can safely withstand 1.0 A and 2.5 A surge (8/20 waveshape as defined in IEC 61000-4-5 2nd edition) at a very low clamping voltage. Provides a moisture and environment barrier to the die which provides ESD protection on I/O and power ports.
