The SM15KPAN Series Delivers Overvoltage Protection in Relay Drives, Motors and Other Applications

TEMPE, Ariz. -- ProTek Devices has introduced its SM15KPAN series of high-powered surface mount transient voltage suppressor (TVS) components to provide overvoltage circuit protection in applications that include relay drives and motor (start/stop) back electromagnetic fields (EMF). The components also deliver module lightning protection and secondary lightning protection for AC/DC power lines.

This series consists of various components, from SM15KPA17AN to SM15KPA220CAN, that make up the family. They have rated stand-off voltages from 17.0 to 220 volts to suit a wide variety of design requirements. The devices provide 15,000 watts of peak pulse power dissipation for a 10/1000 micro amps waveform. They are also compatible with IEC 61000-4-5 (surge): 48A, 8/20 micro amps - L3 (line-ground), L4 (line-line) and L1 (power). The components allow unidirectional and bidirectional configurations as well as easy mounting to a printed circuit board. The clamping time is < 100ps theoretical for unidirectional and 5ns for bidirectional. The series is also RoHS compliant (exemption #7).

The series is provided in a high power surface mountpackage with an approximate weight of only 1.2 grams. The package also has lead-free silver plating. The solder reflow temperature is 240-250 degrees Celsius and the flammability rating is UL 94V-0.

Pricing and Availability
ProTek Devices' SM15KPAN series is now available in mass quantities. Pricing for unidirectional parts start at around $7.75 per part in minimum quantities of 100 units. The bidirectional parts start at $8.50 per part in minimum quantities of 100 units. In addition to the voltages listed in the data sheet, other voltages are also available. Interested parties should contact ProTek Devices' sales department for details: A data sheet for the series can be download at
