PD 1.032A

The PD 1.032A 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 MOSFETdesigns, to eliminate the need for both discrete components and hybrid circuits. The basic SPA Series ChipSwitch PD 1.032A 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 of PD 1.032A 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 PD 1.032A is a single-pole, normally-open SSR capable of switching up to 0.9 ARMS low power factor load currents with precise zero-voltage turn-on and zero-current turn-off, thus reducing EMI emissions.

These PD 1.032A are ideally suited for interfacing microprocessors to AC loads, such as small motors, lamps, solenoids, valves and high power motorstarters. The economy of the SPA Series ChipSwitch PD 1.032A allows the in-house manufacturer to
replace assemblies of triacs, triac drivers and associated components with a highly reliable, miniature, standard SSR.
