General Purpose ESD Protection - SD05C Series
SD05C Series 450W Discrete bidirectional TVS Diode
Description
The bidirectional SD05C TVS diode is designed to replace
multilayer varistors (MLVs) in electronic equipment for low
speed and DC applications. It will protect any sensitive
equipment from damage due to electrostatic discharge
(ESD) and other transient events.
The SD05C can safely absorb repetitive ESD strikes
at ±30kV (contact discharge, IEC 61000-4-2) without
performance degradation and safely dissipate 30A of
8/20μs induced surge current (IEC61000-4-5) with very low
clamping voltages.
