DESCRIPTION
The ILD620, ILQ620, ILD620GB, and ILQ620GB are
multi-channel input phototransistor optocouplers that use
inverse parallel GaAs IRLED emitter and high gain NPN
silicon phototransistors per channel. These devices are
constructed using over/under leadframe optical coupling
and double molded insulation resulting in a withstand test
voltage of 5300 VRMS.
The LED parameters and the linear CTR characteristics
make these devices well suited for AC voltage detection.
The ILD620GB and ILQ620GB with its low IF guaranteed
CTRCEsat minimizes power dissipation of the AC voltage
detection network that is placed in series with the LEDs.
Eliminating the phototransistor base connection provides
added electrical noise immunity from the transients found in
many industrial control environments.
