PAA127 is a dual, high performance, 280V, 200mA,
10, normally open (1-Form-A) Solid State Relay that
has two independently controlled, optically coupled
MOSFET switches in an 8-pin package. It employs
optically coupled MOSFET technology to provide
3750Vrms of input to output isolation.

Features
• 500s Maximum Switching Times
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED.
• High Performance 280VP Blocking Voltage
• Greater Reliability than Electromechanical Relays
• 3750Vrms Input/Output Isolation
• No EMI/RFI Generation
• Low Drive Power Requirements
• Small 8-pin Package
• Surface Mount Tape & Reel Versions Available
This dual single-pole OptoMOS relay provides a more
compact design solution than discrete single-pole
relays in a variety of applications, and saves board
space by incorporating both switches in a single 8-Pin
package.
