ChipSwitch® SIP Relay PD 1.032A SPA Series Microelectronic Power IC Relay 0.9 Amp Load Current, 20 - 280 VACRMS General Description The SPA Series ChipSwitch uses exclusive International Rectifier S3X power integrated circuit technology to form a fully functioning solid-state relay. The S3X technology combines MOS and bipolar processes, derived from IR’s HEXFET® power MOSFET designs, to eliminate the need for both discrete components and hybrid circuits. The basic SPA Series ChipSwitch consists of two identical power integrated circuits connected in inverse parallel (analogous to back-to-back SCRs) for AC control plus an isolated GaAIAs light emitting diode (LED) for actuation.
