5000 V Isolation.
High Current Transfer Ratio (up to 450%).
Low Cost Dual-In-Line Package.
Quad Configuration.
The ISQ203 and ISQ204-1 are optically coupled isolators. Each channel consists of a Gallium Arsenide infrared emitting diode and an NPN silicon phototransistor mounted in a standard 16-pin dual-in-line package. Surface Mount Option Available.
These devices offer four channels per unit.
All electrical parameters are 100% tested by manufacturing. Specifications are guaranteed to a cumulative 0.65% AQL.
