SFH615A-2XSM

Overview

The SFH615A-2XSM is a surface-mount optocoupler manufactured by Isocom Components 2004 LTD. It features a single channel with a transistor output configuration, housed in a 4-SMD Gull Wing package. The device provides electrical isolation of 5300Vrms between the infrared LED input and the NPN silicon phototransistor output. It is designed for applications requiring compact isolation solutions in space-constrained environments.

Feature Summary

• Surface mount construction for automated assembly
• High voltage isolation capability
• Transistor output interface

Applications

• Logic to logic isolation in noisy environments
• Line receiver circuits
• Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix against official Isocom documentation to confirm pinout and packaging variations. Ensure the component meets required safety certifications such as UL or VDE for the target application. Confirm moisture sensitivity levels and storage conditions prior to soldering.

Selection Notes

Select this component when a low-profile surface-mount isolator is required. Compare pin compatibility with legacy through-hole equivalents if replacing existing designs. Verify that the 5300Vrms isolation rating satisfies the system's creepage and clearance requirements.

Part Context

This part belongs to the SFH615A series of optocouplers from Isocom Components. The series includes various package options such as DIP and SMD variants. These devices are commonly used as industry-standard replacements for discontinued optical isolators from other manufacturers.

Replacement Considerations

Check datasheets for compatible alternatives like the SFH615A-2XSMT&R or SFH615A-4X. Ensure substitute parts match the 4-pin configuration and surface-mount footprint. Verify identical isolation voltage ratings before implementation.
