TVS Diode Array (SPA® Diodes)
General Purpose ESD Protection - SD Series
SD Series 450W Discrete Unidirectional TVS Diode
RoHS Pb GREEN
Description
The Unidirectional SD series is designed for use 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 SD series can safely absorb repetitive ESD strikes
at ±30kV (contact discharge, IEC 61000-4-2) without
performance degradation and safely dissipate 30A (SD05)
of 8/20μs induced surge current (IEC61000-4-5 2nd edition)
with very low clamping voltages.
