Semtech Corp. TVS Diodes SMDA15C.TBT

The SMDAxxC series TVS diode array, specifically the part number 58K9956, is designed for bidirectional protection of sensitive electronic components against ESD, lightning, and other transient voltage events. It can protect up to four data or I/O lines and operates at a reverse standoff voltage of 15V, with a maximum clamping voltage of 30V. The device is housed in a low-profile SO-8 package, making it suitable for space-constrained applications. This TVS array meets the ESD immunity requirements of IEC 61000-4-2, level 4, capable of withstanding ±15kV for air discharge and ±8kV for contact discharge. It also provides protection against electrical fast transients (EFT) and lightning strikes, with specified ratings of 40A (5/50ns) and 12A (8/20µs), respectively. The device features low leakage current and solid-state silicon avalanche technology, ensuring no degradation over time. Applications include microprocessor-based equipment, notebooks, desktops, servers, instrumentation, and LAN/WAN equipment. The product is RoHS compliant, making it suitable for environmentally conscious designs.
