SFH615A-4G

Overview

The SFH615A-4G is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It integrates an infrared LED with an NPN silicon phototransistor output. The device provides electrical isolation with a voltage rating of 5300Vrms. It features a current transfer ratio ranging from 160% to 320%. The maximum collector-emitter voltage is 70V, and the output current capacity is 50mA. The component is housed in a 4-pin DIP package.

Feature Summary

• Integrates an infrared light emitting diode with an NPN silicon phototransistor for signal transmission.
• Provides high-voltage electrical isolation between input and output circuits.
• Designed for general-purpose logic-to-logic isolation applications.

Applications

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

Procurement Notes

Verify that the ordering suffix '-4G' corresponds to the specific tape-and-reel packaging configuration as defined by the manufacturer. Confirm that the component meets RoHS compliance standards required for the target assembly process. Ensure the supplier provides valid traceability documentation for the Isocom Components 2004 LTD origin.

Selection Notes

Select this component when a single-channel transistor output isolator is required with a 5300Vrms isolation capability. Consider the 70V output voltage limit and 50mA current drive capacity for load matching. Verify compatibility with standard DIP-4 footprints during PCB layout design.

Part Context

This part belongs to the SFH615A series of optocouplers produced by Isocom Components 2004 LTD. The series includes variants with different pin counts and package types, such as the SFH615A-2X and SFH615A-4XSM. These devices are designed as industry-standard replacements for legacy optocoupler models.

Replacement Considerations

The SFH615A-4XSM is a surface-mount variant within the same product family offering similar electrical characteristics in an SDIP-4 package.
