General Purpose ESD Protection - SP1054

Description

Applications

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 ±30kV (contact discharge, IEC 61000-4-2) without

performance degradation. Additionally, each diode can

safely withstand 2.5A surge (8/20 waveshape as defined
