SFH615A-2XG

Overview

The SFH615A-2XG is a single-channel optocoupler manufactured by Isocom Components, designed as a direct replacement for the Vishay SFH615A. It features an NPN phototransistor output and utilizes a standard DIP-4 through-hole package. The device provides electrical isolation with a rated voltage of 5000 Vrms. Key electrical characteristics include a minimum current transfer ratio (CTR) of 160% at a forward current of 10 mA, a maximum collector-emitter saturation voltage of 300 mV, and a continuous output current capability of 50 mA. The unit operates within a temperature range of -30°C to +100°C.

Feature Summary

• Provides high-speed switching performance suitable for digital signal transmission applications
• Offers robust galvanic isolation between input and output circuits
• Ensures compatibility with standard DIP-4 footprint layouts

Applications

• Logic-to-logic isolation in noisy industrial environments
• Line receiver circuits
• Programmable current level sensors
• Digital control interfaces for motors and servo machines

Procurement Notes

Verify that the ordering suffix matches the required package style and compliance standards. Confirm the manufacturer designation aligns with Isocom Components specifications rather than original equipment manufacturer markings. Ensure the component meets RoHS directives if required by the design specification. Cross-reference datasheet parameters against the specific batch documentation to guarantee performance consistency.

Selection Notes

Select this component when a direct pin-compatible substitute for the Vishay SFH615A is required. The NPN phototransistor output configuration supports standard logic interfacing. Verify that the 5000 Vrms isolation rating satisfies the safety requirements of the target application. Consider the operating temperature range limits during thermal analysis of the final assembly.

Part Context

This part belongs to the SFH615A series of transistor output optocouplers. Isocom Components specializes in providing industry-standard alternatives and end-of-life replacements for discontinued semiconductor devices. The series is engineered to maintain identical mechanical dimensions and electrical performance profiles as the original referenced components.

Replacement Considerations

This component serves as a verified alternative to the Vishay SFH615A-2XSM. Both parts share identical pin configurations and functional specifications. Designers should confirm that the supplier's version meets all relevant UL and VDE certification requirements applicable to the original device.
