Pb
SP1054 25pF 30kV 01005 DFN Plastic Unidirectional Discrete TVS
Description
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 ±±3kꢀ (contact discharge, IEC 61333-4-2) without
performance degradation. Additionally, each diode can
safely withstand 2.5A surge (8/23 waveshape as defined
in IEC 61333-4-5 2nd edition) at a very low clamping voltage.
