TVS Diode Arrays (SPA® Diodes)
General Purpose ESD Protection - SM05 through SM36
SM Series 400W TVS Diode Array
RoHS Pb GREEN
The SM series TVS Diode Array is designed to protect
sensitive equipment from damage due to electrostatic
discharge (ESD), electrical fast transients (EFT), and
lightning induced surges.
The SM series can absorb repetitive ESD strikes above the
maximum level specified in the IEC 61000-4-2 international
standard without performance degradation and safely
dissipate up to 24A of 8/20µs induced surge current (IEC-
61000-4-5, 2nd Edition) with very low clamping voltages.
