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 Interna-
tional Rectifier S3X power integrated circuit technol-
ogy to form a fully functioning solid-state relay. The
S3X technology combines MOS and bipolar pro-
cesses, derived from IR’s HEXFET® power MOS-
FET 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.
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 precise
zero-voltage turn-on and zero-current turn-off, thus
reducing EMI emissions.
These devices 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 SPA Series
ChipSwitch allows the in-house manufacturer to
replace assemblies of triacs, triac drivers and
associated components with a highly reliable,
miniature, standard SSR.
