TDS SurgeSwitch™ Surge Suppressors

Semtech TDS SurgeSwitch™ Surge Suppressors are designed to protect circuits and systems operating in harsh industrial and telecom environments. Unlike conventional transient voltage suppressor (TVS) diodes, Semtech TDS SurgeSwitch devices maintain nearly the same clamping voltage over the entire peak pulse current range and extended temperature range, using an innovative architecture. These surge suppressors feature operating voltages of 22V, 30V, 33V, 40V, 45V, and 58V and are housed in a small 1.6mm x 1mm package. The devices may be used to meet the common industrial voltage surge standard of ±1kV per IEC61000-4-5 (RS = 42Ω, CS = 0.5μF).
