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.
Identical channel to channel footprint
ILD620 crosses to TLP620-2
ILQ620 crosses to TLP620-4
High collector emitter voltage, BVCEO = 70 V
Dual and quad packages feature: - Reduced board space - Lower pin and parts count - Better channel to channel CTR match - Improved common mode rejection
