Overview
The SFH615A-2 is a single-channel transistor output optocoupler manufactured by Isocom Components. It features an NPN phototransistor output and utilizes a DIP-4 through-hole package. The device provides high isolation voltage of 5300 Vrms, ensuring reliable signal transmission in electrically noisy environments. Key electrical parameters include a collector-emitter breakdown voltage of 70V and a maximum collector current of 50mA. The typical forward voltage is 1.65V, with a minimum current transfer ratio of 100% at 10mA input current. Operating temperatures range from -55°C to +100°C.
Feature Summary
- Provides galvanic isolation between input and output circuits using an infrared LED and NPN phototransistor configuration.
- Offers high reliability and long-term stability suitable for industrial applications requiring robust signal integrity.
- Complies with international safety standards including UL recognition and VDE approval for enhanced operational safety.
Applications
- Logic-to-logic isolation in noisy industrial environments
- Line receiver circuits for signal transmission
- Programmable current level sensing applications
- Digital control systems for motors and servo machines
Procurement Notes
Verify the manufacturer origin carefully, as Isocom specializes in industry-standard replacements. Confirm that the specific suffix matches the required pinout and electrical characteristics. Ensure compliance with RoHS directives if environmental regulations apply to your project. Cross-reference datasheets to confirm compatibility with existing circuit designs before finalizing procurement decisions.
Selection Notes
Select this component when a standard DIP-4 package is required for through-hole mounting. Consider the 5300 Vrms isolation rating for applications demanding high voltage separation. Evaluate the NPN output type against system logic requirements. Verify thermal performance within the specified operating temperature range to ensure consistent functionality under varying environmental conditions.
Part Context
This part belongs to the SFH615A series, which are widely recognized as alternatives to Vishay components. Isocom focuses on providing commercial equivalents and end-of-life replacements for established optocoupler models. The series is designed to meet industry standards while offering flexibility in electrical parameter adjustments based on customer needs.
Replacement Considerations
The VO615A-2X009T is a confirmed public substitute part number for this component. Both parts share identical functional specifications and pin configurations. Designers may consider this alternative for supply chain diversification or availability reasons without modifying the circuit layout.
