Semtech RClamp04022S RailClamp® 2-Line TVS Diode
Semtech RClamp04022S RailClamp® 2-Line TVS Diode is designed to protect sensitive electronics from damage or latch-up due to electrostatic discharge (ESD) and electrical overstress (EOS). The Semtech RClamp04022S features a large cross-sectional area junction for conducting high transient currents. The diode offers desirable characteristics for board-level protection, including fast response time, a low operating/clamping voltage, and no device degradation. RClamp04022S is in a SOT23-3 lead package with lead-free matte tin finished leads. This device may be used to meet the ESD immunity requirements of IEC 61000-4-2 (±30kV air, ±30kV contact discharge). Low maximum capacitance (0.75pF at VR=0V) minimizes loading on sensitive circuits. Each device will protect two high-speed data lines operating at 4V.
