TLP628, TLP628−2, TLP628−4 are Toshiba's photocoupler products, consisting of a gallium arsenide infrared emitting diode optically coupled to a phototransistor with a 350V high voltage of collector-emitter breakdown voltage. TLP628−2 offers two isolated channels in an eight-lead plastic DIP package, while TLP628−4 provides four isolated channels in one package of the same type.
The Toshiba TLP628 series includes the TLP628, TLP628‑2 and TLP628‑4 GaAs infrared photocouplers. Each device combines an infrared emitting diode with a phototransistor, offering high isolation and current transfer capabilities.
