ProTek Devices Adds TVS Modules for Military-Aerospace and Industrial Circuit Protection
SM15KWE Series and SM30KWE Series Press Release
The Newest TVS Components Double ProTek Devices’ 2022 Circuit Protection Offerings for Military / Aerospace and Industrial Application Circuit Protection for Transients Like High Voltage Spikes.
ProTek Devices has added circuit protection devices to its family of high-powered surface mount transient voltage suppression components that provide circuit protection in numerous military / aerospace and industrial applications. These applications include relay drives, motor start-and-stop electromagnetic field protection, module lightning protection, and secondary lightning protection in AC/DC applications.
The new addition is the SM15KWExxA/CA series. Together with the SM30KWExxA/CA series introduced in March, the family of TVS components provide broad circuit protection for across military / aerospace and industrial applications. Both families of products are now currently sampling. The SM15KWExxA/CA series consists of around a dozen devices with rated stand-off voltages from 15.0 to 78.0 volts. The SM30KWExxA/CA series of TVS components also have around a dozen device options with rated stand-off voltages from 16.0 to 78.0 volts.
The parts all boast compliance with the standard for environmental conditions and test procedures for airborne equipment, RTCA DO-160G. Specifically, they meet section 22 for lightning induced transient susceptibility. The test methods and procedures help verify the capability of equipment to withstand a selection of transients defined in the section, intended to represent induced effects of lightning.
In addition, the newest SM15KWExxA/CA series is compatible with IEC standards 61000-4-2 (ESD): air plus or minus 15kV, contact plus or minus 8kV; with 61000-4-4 (EFT): 40A, 5/50 ns; and with 61000-4-5 (surge): 60kW, 8/20 microseconds. It provides 15 kilowatts peak pulse power per line (typical = 10/1000 microseconds). It also boasts unidirectional and bidirectional configurations while also allowing for easy mounting to a printed circuit board. Finally, the SM15KWExxA/CA series is RoHS and REACH compliant.
The SM30KWExxA/CA series features waveforms (pin injection) three and four – level five; and waveform 5A – level four. Other features include a low clamping voltage and 30 kilowatts peak pulse power per line (typical = 10/1000 microseconds). In addition, they provide engineers with the ability for unidirectional and bidirectional configurations and easy mounting on printed circuit boards. These parts are all also RoHS and REACH compliant.
