El dispositivo acopla ópticamente un diodo emisor de infrarrojos de arseniuro de galio (GaAs IRED) en la entrada con un fototransistor de silicio NPN de alta tensión en la salida, proporcionando un aislamiento galvánico de 5000 Vrms entre circuitos lógicos digitales y entornos industriales de alta tensión. La serie moderna PC817X cuenta con una tensión de ruptura colector-emisor (VCEO) de 80 V y una corriente continua de colector de 50 mA, siendo ideal para el desacoplo de ruido en fuentes conmutadas (SMPS), aislamiento de entradas de microcontroladores frente a líneas de campo PLC de 24 V y control de transistores de relés sin bucles de masa. La relación de transferencia de corriente (CTR) se clasifica en cuatro rangos normalizados: Rango A (80%..160%), Rango B (130%..260%), Rango C (200%..400%) y Rango D (300%..600%) medidos a IF = 5 mA y VCE = 5 V.
