DPA6119

The DPA Series ChipSwitch DPA6119 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 DPA Series ChipSwitch DPA6119 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. Voltage controlled models with an internal resistor to limit the control current are also available.

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 DPA Series ChipSwitch DPA6119 is a single-pole,normally-open SSR capable of switching up to 1.0 ARMS load currents with precise zero-voltage turnon and zero-current turn-off, thus reducing EMI emissions.

These DPA6119s are ideally suited for interfacing microprocessors to AC loads, such as small motors,lamps, solenoids, valves and high power motor starters. The economy of the DPA Series ChipSwitch allows the in-house manufacturer to replace assemblies of triacs, triac drivers and associated components with a highly reliable,miniature, standard SSR.
