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