SM15KPA17A - SM15KPA220CA
15kW SURFACE MOUNT POWER TVS COMPONENT
DESCRIPTION
The SM15KPA Series are high-powered surface mount transient voltage suppression components designed to protect
equipment and systems from the damaging eects of high voltage spikes. The surface mount package conguraon
provides a lower prole at a reduce cost compared to legacy axial lead package conguraons.
These devices provide 15,000 Was of peak pulse power dissipaon for an 10/1000µs waveform. Applicaons in-
clude AC and DC power line protecon, terrestrial base staon protecon as well as module lightning protecon.
FEATURES
• Compable with IEC 61000-4-5 (Surge): 48A, 8/20µs - L3(Line-
Ground), L4(Line-Line) & L1 (Power)
• 15,000 Was Peak Pulse Power per Line (tp = 10/1000µs)
• Unidireconal and Bidireconal Conguraons
• Easy Mounng to Printed Circuit Board
• Available in Mulple Voltages
• tClamping (0V to V
(BR)
Min) < 100ps, Theorecal for Unidireconal and
5ns for Bidireconal
• RoHS Complaint (Exempon #7)
• This series will connue to be supplied to current and/or new
designs. However, ProTek recommends the SM15KPAxxxAN/CAN
Series to be used in newer designs
MECHANICAL CHARACTERISTICS
