Overview
The SFH615A-4X is a single-channel transistor output optocoupler manufactured by Isocom Components. It features an NPN phototransistor output with a collector-emitter breakdown voltage of 70V and a maximum continuous collector current of 50mA. The device provides high isolation capability, rated at 5000 Vrms or 5300V peak, ensuring safety in demanding environments. It operates within a temperature range of -55°C to 100°C and complies with RoHS standards.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared LED technology.
- Features a robust NPN phototransistor output stage for reliable signal switching.
- Designed for high reliability with UL recognition and VDE approval certifications.
Applications
- Logic-to-logic isolation in noisy industrial environments
- Line receiver circuits for communication interfaces
- Programmable current level sensing applications
- Digital control of motors and servo machines
Procurement Notes
Verify the specific suffix (e.g., XSM, X001T) against official datasheets to confirm package type and CTR binning. Ensure compliance requirements such as RoHS and REACH are met for the target region. Cross-reference manufacturer part numbers carefully, as Isocom may supply rebranded Vishay components; always validate the source document's part identification.
Selection Notes
Select this component when high isolation voltage and standard NPN output characteristics are required. Consider the 70V collector voltage limit and 50mA current capacity for load matching. Verify thermal management needs for operation near the upper temperature limit. Confirm that the specific suffix matches the desired packaging format and electrical parameter tolerances defined in the official specification.
Part Context
Isocom Components specializes in optocouplers and has historically supplied industry-standard replacements. The SFH615A series represents their portfolio of plastic commercial products, often sourced from major semiconductor manufacturers like Vishay. This part fits into their strategy of providing accessible alternatives for discontinued or legacy optical isolation devices.
Replacement Considerations
The VO615A-4 is a confirmed equivalent part number from Vishay Semiconductors. Both parts share identical pinouts, electrical specifications, and isolation ratings. Designers can typically substitute one for the other without circuit modification, provided the specific suffix variations are accounted for.
