International Rectifier SPA4191
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.| Part No. | SPA4191 |

GENERAL DESCRIPTION
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. Extreme reliability is achieved by the reduction of component count from approximately 20 discrete components in a conventional SSR to 3 basic components in the ChipSwitch. The SPA Series ChipSwitch is a single-pole, normally-open SSR capable of switching up to 0.9 ARMS low power factor load currents with
