ILD621 Description

Short technical summary and product information.

The ILD621 series from Vishay Dale are multi-channel phototransistor optocouplers designed for various isolation applications. These devices employ GaAs IRED emitters coupled with high gain NPN silicon phototransistors, constructed using double molded insulation technology for enhanced reliability.

A key electrical characteristic is the high collector-emitter voltage rating of 80V, making it suitable for applications requiring significant voltage standoff. The dual and quad channel packages offer advantages such as reduced pin and parts count, improved channel-to-channel CTR matching, and enhanced common mode rejection.

These optocouplers are available in DIP and SMD package types, supporting both through-hole and surface-mount assembly methods. The ILD621 series is agency certified by UL, cUL, CSA, CQC, and FIMKO, with options for VDE certification.

Material categorization information is available, and the devices are RoHS3 compliant. The ILD621 is designed for applications where electrical isolation is critical, leveraging its phototransistor output for signal coupling.
