Additional Details

The SC609IMLTR utilizes Semtech's proprietary technology to provide superior surge protection performance. It features a transient voltage suppressor (TVS) diode that clamps the voltage to a safe level during a surge event. This prevents the voltage from exceeding the maximum rating of the protected components. The device is available in a small surface-mount package for easy PCB assembly. Key specifications include a standoff voltage of typically around 9V, a clamping voltage of around 15V (depending on surge current), and a peak pulse current rating. The specific clamping voltage will vary with the magnitude and waveform of the surge current. It's suitable for protecting against ESD, EFT, and lightning surges as defined in IEC standards such as IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge). Proper PCB layout and grounding techniques are important for optimal surge protection performance.
