P0640ECL, Thyristor Surge Protection Devices - TSPD 500A 58V
Circuit Protection\Thyristors\Thyristor Surge Protection Devices - TSPDSIDACtor® Baseband Protection Thyristors Littelfuse SIDACtor Baseband Protection Thyristors are solid state crowbar devices designed to protect of baseband telecommunications equipment such as phones, faxes, modems, line cards, CPE and DSL from damaging overvoltage transients. Leveraging the latest in thyristor advancements, Littelfuse offers SIDACtor devices with a patented ion implant technology. This technology ensures effective protection within nanoseconds, up to 3000 A 1.2-50-8/20 surge current ratings, and simple solutions for regulatory requirements such as GR 1089, TIA-968-B (formerly known as FCC Part 68), ITU-T K.20, ITU-T K.21, and UL 60950-1. In the standby mode, SIDACtor devices exhibit a high off-state impedance, eliminating excessive leakage currents and appearing transparent to the circuits they protect. If a voltage exceeding the switching voltage (VS) occurs, the SIDACtor devices crowbar and simulate a short circuit condition until the current flowing through the device is either interrupted or drops below the SIDACtor device's holding current (IH). When this occurs, SIDACtor devices reset and return to their high off-state impedance. NEW! Littelfuse expanded its SIDACtor Baseband Protection Thyristors product line to include the low profile SMA Series which features excellent surge rating, low voltage overshoot, and low capacitance, a smaller SMA package, and does not degrade surge capability after multiple events.
