ILQ621GB Description

Short technical summary and product information.

The Vishay Dale ILQ621GB is a multi-channel optocoupler featuring four channels with phototransistor outputs. It utilizes GaAs IRED emitters and high gain NPN silicon phototransistors, constructed with double molded insulation technology. This device is suitable for applications requiring electrical isolation, offering a high isolation rating of 4420 VRMS.

 

Key electrical characteristics include a minimum Current Transfer Ratio (CTR) of 100% at 5mA and a maximum CTR of 600% at 5mA. The Vce Saturation is a maximum of 400mV, and it handles a maximum input current of 60mA. The optocoupler has a high collector emitter voltage (BVCEO) of 70V.

 

Designed for through-hole mounting, the ILQ621GB comes in a 16-DIP package. It operates across a wide temperature range from -55°C to 100°C, making it suitable for various environmental conditions. The device is an alternate source to TLP621-2, TLP621-4, TLP621GB-2, and TLP621GB-4.

 

This optocoupler is well-suited for applications such as power supply feedback circuits where stable DC gain is essential. Its dual and quad packages offer reduced pin and parts count, improved channel-to-channel CTR match, and enhanced common mode rejection.
