Overview
The SFH610A-5 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output housed in a DIP-4 through-hole package. Key electrical specifications include a maximum collector-emitter voltage of 70 V, a maximum collector current of 100 mA, and a power dissipation of 150 mW. The device offers a high current transfer ratio ranging from 250% to 500%, with a forward current of 60 mA and a forward voltage of 1.65 V. Isolation voltage is rated at 5300 Vrms, and it operates within a temperature range of -55°C to +100°C.
Feature Summary
- High current transfer ratio for enhanced signal transmission efficiency
- Robust insulation performance suitable for high-voltage isolation applications
- Low saturation voltage to minimize power loss in the output stage
Applications
- Industrial control systems requiring galvanic isolation
- Signal coupling in measurement and testing equipment
- Power supply feedback loops for voltage regulation
Procurement Notes
Verify component authenticity by checking manufacturer markings and datasheet alignment. Confirm RoHS compliance status as indicated in official documentation. Ensure storage conditions maintain integrity prior to assembly. Cross-reference ordering suffixes with Vishay's official naming conventions to avoid variant mismatches during procurement.
Selection Notes
Select this model when high current transfer ratio and robust isolation are required. Consider the 70 V collector-emitter voltage limit for circuit design. Evaluate thermal management needs given the 150 mW power dissipation rating. Compare against lower CTR variants if signal gain requirements differ. Ensure DIP-4 package compatibility with existing PCB layouts.
Part Context
The SFH610A-5 belongs to the SFH610 series of transistor output optocouplers. This series provides reliable galvanic isolation between input and output circuits. The component is designed for general-purpose switching and signal transmission applications where high reliability and electrical safety are critical parameters.
Replacement Considerations
SFH610A-1 and SFH610A-2 are alternative variants within the same family. Note that these alternatives offer different current transfer ratio ranges compared to the SFH610A-5. Verify pinout compatibility and electrical parameter differences before substitution.
