IS604X

Overview

The IS604X is a single-channel AC input-transistor output optocoupler manufactured by Isocom Components. It features a surface mount plastic package with six pins and provides high isolation capability of 5300 Vrms between the input LED and output transistor. The device supports a maximum forward current of 100 mA and a typical current transfer ratio of 50%. It operates within a temperature range of -55°C to +100°C, includes UL recognition, and complies with RoHS standards.

Feature Summary

• AC input configuration for direct mains or AC signal interfacing
• High voltage isolation barrier rated at 5300 Vrms
• Surface mount packaging for automated assembly processes

Applications

• Industrial control systems requiring AC signal isolation
• Solid-state relay driver circuits
• Power supply feedback loops

Procurement Notes

Verify that the specific suffix matches the required surface mount variant. Confirm compliance with RoHS directives and UL recognition status for safety-critical designs. Ensure the operating temperature range meets environmental requirements. Check pinout compatibility with target PCB footprint before integration.

Selection Notes

Select this component when AC input detection is required without external rectification. The high isolation voltage suits applications with significant potential differences. Consider the 50% CTR for driving logic inputs directly. Evaluate thermal management needs given the 100°C upper limit.

Part Context

Isocom Components specializes in infrared optoelectronic devices and offers the IS604X as part of their general-purpose optocoupler portfolio. This series targets replacements for legacy components while providing modern surface mount options. The manufacturer emphasizes flexible manufacturing and global industry standard adherence.
