ProTek Devices Intros Industry-First Smaller Profile Circuit Protection TVS Components
SM15KWE Series Press Release
ProTek Devices has introduced a series of high-powered surface mount TVS components for circuit protection from electromagnetic field, lightning, and other electrical fast transients in high power applications. These new devices for motors and relays are provided in that industry’s lowest-profile packaging compared with competing solutions.
ProTek Devices’ SM15KWExxA/CA series have an approximate weight of just 2.5 grams and the components come in a molded DFN-2-KW package. This provides a space-saving feature with no performance penalties compared with competing surface mount technology solutions.
The SM15KWExxA/CA series are ideal for motor start-and-stop EMF protection and with relay drives. The series provides 15 kilowatts of peak pulse power dissipation for an 10/1000 microsecond waveform.
The SM15KWExxA/CA series are RTCA DO-160G compliant. They are also compatible with IEC standards 61000-4-2 (ESD): air +/-15kV, Contact +/-8kV; with 61000-4-4 (EFT): 40A, 5/50ns; and with 61000-4-5 (surge): 60kW, 8/20 microseconds. And they are also RoHS and REACH compliant.
The devices offer unidirectional and bidirectional configurations and easy mounting to a printed circuit board. The series consists of five components, ranging from 24V to 70V. These include part numbers SM15KWE24A for 24V, SM15KWE30A at 30V, SM15KWE36A at 36V, the SM15KWE48A at 48V, and the SM15KWE70A at 70V.
