Optocouplers-
Phototransistor Optocouplers

Phototransistor optocouplers are primarily used for optical isolation, high current transfer ratio, and low saturation Vce. Each unit consists of a light emitting diode and a N-P-N silicon phototransistor mounted and coupled in a miniature custom substrate for hybrid assembly or in hermetically sealed packages.
