DPA4111
Description
The DPA 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 DPA 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. Voltage controlled models with an internal resistor to limit the control current are also available. 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 DPA Series Chip Switch 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,...
