Power switch, CPC40055ST, LITTELFUSE

An AC solid-state switch utilizing dual power SCR outputs. This device includes zero-cross turn-on circuitry and is specified with an 800 VP blocking voltage. Tightly controlled zero-cross circuitry ensures low-noise switching of AC loads by minimizing the generation of transients. The optically coupled input and output circuits provide exceptional noise immunity and 2500 Vrms of isolation. As a result, it's well suited for industrial environments where electromagnetic interference would disrupt the operation of communications and control systems. The unique SuperSIP package pioneered by IXYS integrated circuits allows solid-state relays to achieve the highest load current currently available in any similar-sized package. This package features a unique process in which the silicon chips are softly soldered onto the ceramic direct copper bond (DCB) substrate instead of the traditional copper leadframe. The DCB ceramic, the same substrate used in high-power modules, not only provides 2500 Vrms isolation but also very low junction-to-case thermal impedance (0.35 °C/W).
