Overview
The SFH617A-2X is a single-channel transistor output optocoupler manufactured by Isocom Components. It provides electrical isolation via an infrared LED and NPN phototransistor. The device features a 5300 Vrms insulation voltage rating, suitable for high-voltage noise immunity applications. It supports a maximum forward current of 60 mA and offers a collector-emitter saturation voltage of 250 mV. The component operates within a temperature range of -55°C to +110°C and is available in surface-mount packages.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared light transmission
- Features a high insulation voltage rating for robust noise immunity in sensitive environments
- Utilizes an NPN phototransistor output stage for reliable digital signal switching
Applications
- Logic-to-logic isolation in noisy industrial environments
- Line receiver circuits requiring signal integrity
- Digital control interfaces for motors and servo machines
Procurement Notes
Verify the specific suffix designation (e.g., X009T) against official datasheets to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and verify UL/VDE certifications required for end-product safety approvals. Cross-reference manufacturer part numbers with distributor listings to confirm availability and authenticity.
Selection Notes
Select this component when high isolation voltage and wide operating temperature ranges are critical. Compare current transfer ratio specifications against load requirements to ensure adequate drive capability. Evaluate package dimensions for PCB layout constraints and consider thermal dissipation limits under continuous operation conditions.
Part Context
Isocom Components specializes in industry-standard replacements for discontinued optocouplers. The SFH617 series serves as a direct alternative to legacy Vishay devices, maintaining identical pinouts and electrical characteristics. This lineage ensures compatibility with existing designs while offering supply chain stability through established manufacturing partnerships.
Replacement Considerations
The VO617A-2 is a confirmed substitute part number from Vishay Semiconductors. Verify pinout alignment and parameter tolerances before implementation.
