Overview
The SFH615AA is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and provides high isolation voltage of 5300 Vrms. The device operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter breakdown voltage of 70V, a maximum forward current of 60mA, and a typical forward voltage of 1.25V. The component supports a maximum collector current of 50mA with a saturation voltage of 400mV. Current transfer ratio ranges from 50% to 600% depending on the specific variant.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes a single-channel NPN phototransistor for signal transmission
- Designed for high reliability applications requiring robust performance
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal isolation in microprocessor interfaces
Procurement Notes
Verify the specific suffix (e.g., X001, X007) to confirm package type and CTR specifications. Ensure compliance with RoHS directives as indicated in official documentation. Confirm lead time and availability directly with authorized distributors. Validate that the selected variant matches the required isolation voltage and operating temperature range for the target application.
Selection Notes
Select the SFH615AA variant based on the required current transfer ratio and packaging preference. DIP-4 packages are suitable for through-hole mounting, while SMD options exist for surface mount applications. Consider the operating temperature range and isolation requirements when choosing between different CTR grades. Ensure the forward current limits are respected in the circuit design.
Part Context
The SFH615AA belongs to Vishay's family of high-reliability optocouplers. These components are designed for applications demanding robust isolation and long-term stability. The series includes various suffixes indicating different packaging and performance characteristics. They are widely used in industrial and commercial electronics where safety and signal integrity are critical.
Replacement Considerations
Direct substitutes may include other Vishay models within the SFH615 series or equivalent parts from manufacturers like ON Semiconductor. Verify pinout compatibility and electrical parameter equivalence before substitution. Check datasheets for differences in switching times and isolation ratings.
