ProTek Devices' Adds New Series to its High Power Surface Mount Package TVS Components

February 18, 2014

The SM30KPAN Series Provides 30,000 Watts Peak Pulse Power Dissipation for Relay Drives, Motors and Other Applications

TEMPE, AZ -- ProTek Devices has introduced its SM30KPAN series of high-powered surface mount transient voltage suppressor (TVS) components to provide circuit protection from overvoltage events 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 SM30KPA30AN to SM30KPA75AN, that make up the family. They have rated stand-off voltages from 30.0 to 75.0 volts to suit a wide variety of design requirements. The devices provide 30,000 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 RoHS compliant (exemption #7). It is provided in a high power surface mountpackage with an approximate weight of only 4 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' SM30KPAN series is now available in mass quantities. Pricing for unidirectional parts start at around $11 per part in minimum quantities of 100 units. The bidirectional parts start at $13 per part in minimum quantities of 100 units. In addition to the voltages listed in the data sheet, other voltages are available.
