CorpThe PS2801-1-F3 with Transistor Output Optocouplers OPTOCOUPLER 4-PIN SSOP manufactured by Renesas Corp is an optocoupler which uses a light emitting diode to optically isolate two circuits. It has a 4-pin configuration and is shipped in a SSOP (small outline package) package for surface mounting. Its Transistor Output Optocoupler configuration means it can drive heavier loads and is suitable for power switching applications. It has guaranteed CTR up to 200% and maximum collector-emitter voltage of 30V, suitable for high voltage needs. Its PC board mounting supports 17 different clearances and creepage. It complies with UL, CSA, EN, VDE and several other safety standards.
