IS4600

Overview

The IS4600 is a quad-channel optocoupler manufactured by Isocom Components 2004 LTD. It features four independent channels, each comprising two infrared emitting diodes connected in reverse parallel and optically coupled to NPN silicon phototransistors. The device is housed in a 16-pin SOP package. Key electrical specifications include a maximum forward current of 50 mA per channel and an isolation voltage rating of 3750 Vrms.

Feature Summary

• Quad-channel architecture with dual infrared emitters per channel for enhanced reliability
• NPN silicon phototransistor output configuration
• High insulation voltage capability for robust signal isolation

Applications

• Industrial control systems requiring multi-channel isolation
• Power supply protection circuits
• Data communication interfaces

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as manufacturers may offer different mechanical or electrical sub-types under the same base number. Confirm that the 3750 Vrms isolation rating meets your system's safety requirements. Ensure compatibility with standard SOP-16 footprints during PCB layout. Cross-reference datasheets from authorized distributors to confirm current production status and lead times.

Selection Notes

Select this component when multiple isolated channels are required within a single footprint. The dual-diode input design offers redundancy compared to single-emitter alternatives. Consider the 50 mA drive requirement for input circuitry design. Verify thermal management needs based on the SOP-16 package constraints. Ensure the NPN output type aligns with the receiving logic or interface requirements.
