DESCRIPTION
The ILD/Q620 and ILD/Q620GB are multi-channel input phototransistor optocouplers that use inverse parallel GaAs IRLED emitters 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.

FEATURES
• Identical Channel to Channel Footprint ILD620 Crosses to TLP620-2 ILQ620 Crosses to TLP620-4
• Current Transfer Ratio (CTR) at IF= ±5.0 mA ILD/Q620: 50% Min. ILD/Q620GB: 100% Min.
• Saturated Current Transfer Ratio (CTRSAT) at IF= ±1.0 mA ILD/Q620: 60% Typ. ILD/Q620GB: 30% Min.
