ILD621 MULTI-CHANNEL PHOTOTRANSISTOR OPTOCOUPLER

The ILD/Q621 and ILD/Q621GB are multi-channel phototransistor optocouplers that use GaAs IRLED emitters and high gain NPN silicon phototransistors. These devices are constructed using over/under leadframe optical coupling and double molded insulation technology. This assembly process offers a withstand test voltage of 7500 VDC. The ILD/Q621GB is well suited .
