Overview
The SFH609-4 is a single-channel transistor output optocoupler manufactured by Isocom Components. It features an infrared LED coupled to an NPN silicon phototransistor in a 6-pin DIP package. Key electrical parameters include a maximum isolation voltage of 2800 V, a minimum collector-emitter breakdown voltage (BVCEO) of 70 V, and a rated current transfer ratio of 40%. The device supports a maximum forward current of 60 mA and operates within a temperature range of -55°C to 100°C.
Feature Summary
- Provides optical isolation between input and output circuits using an infrared LED and NPN phototransistor configuration.
- Features high collector-emitter breakdown voltage capability for robust signal transmission across different potentials.
- Available in space-efficient dual in-line plastic packages with options for standard, G-form, and surface mount configurations.
Applications
- Industrial systems controllers
- Computer terminals
- Measuring instruments
- Signal transmission between systems of different potentials and impedances
Procurement Notes
Verify the specific suffix designation to confirm the lead form and package type, as the SFH609 series includes STD, G-form, and SMD variants. Ensure compliance requirements such as UL recognition and VDE approval are confirmed against the specific orderable part number documentation before procurement.
Selection Notes
Select this component when a single-channel transistor output isolator with a 6-pin DIP footprint is required. Consider the 2800 V isolation rating and 70 V BVCEO for applications requiring moderate isolation strength. Evaluate the 40% CTR and 60 mA max forward current against system drive capabilities.
Part Context
The SFH609-4 belongs to the SFH609 series of optically coupled isolators produced by Isocom Components. This series is designed for general-purpose signal isolation and is certified under various safety standards including UL and VDE. The product line offers multiple packaging options to suit different assembly requirements.
Replacement Considerations
Cross-reference with other single-channel transistor output optocouplers featuring 6-pin DIP packages and similar isolation voltages. Verify pinout compatibility and electrical parameter margins, specifically CTR and BVCEO, when substituting with equivalent components from other manufacturers.
