Chip Switch® SIP Relay PD 1.032A SPA Series Microelectronic Power IC Relay 0.9 Amp Load Current, 20 - 280 VACRMS General Description The SPA Series Chip Switch uses exclusive International Rectifier S3X power integrated circuit technology to form a fully functioning solid-state relay. The S3X technology bines MOS and bipolar processes, derived from IR’s HEXFET® power MOSFET designs, to eliminate the need for both discrete ponents and hybrid circuits. The basic SPA Series Chip Switch consists of two identical power integrated circuits connected in inverse parallel (analogous to back-to-back SCRs) for AC control plus an isolated Ga AIAs light emitting diode (LED) for actuation. Extreme reliability is achieved by the reduction of ponent count from approximately 20 discrete ponents in a conventional SSR to 3 basic ponents in the Chip Switch. The SPA Series Chip Switch is a single-pole, normally-open SSR capable of switching up to 0.9 ARMS low power factor load currents...
