ProTek Devices Intros High Voltage Suppression Component for Aerospace and Industrial

SM100KWE78CA Press Release

The New Component is Suited to Guard Against High Voltage Spikes, Like Lightning, in Motors to Aircraft AC/DC Systems and More

ProTek Devices has created a high-powered surface mount transient voltage suppression component designed for motor, module, and AC/DC systems such as those in aircraft, to enable equipment circuit protection from damaging effects of high voltage spikes. It is provided in a surface mount package that features a lower profile compared to legacy axial lead package configurations.

More specifically, the new SM100KWE78CA component is ideal for use with relay drives, for motor (start/stop) back EMF protection, with module lightning protection, and with secondary lightning protection for AC/DC systems. The new product is RTCA DO-160G compliant.

Technical capabilities include waveforms (pin Injection) 3 and 4 – level 5; waveform 5A – level 6 (2000V/2000A). It also has a low clamping voltage and allows 100 kilowatts peak pulse power per line (typical = 10/1000 microseconds). It permits a bidirectional configuration and easy mounting to a printed circuit board. The minimum breakdown voltage is 78V. For other voltages, customers can inquire with ProTek Devices or its distributors. The SM100KWE78CA is also RoHS and REACH compliant.
