SFH615A-2X009T

Overview

The SFH615A-2X009T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a current transfer ratio ranging from 63% to 125%. The device provides high isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a forward current of 60 mA. The component is housed in a compact 4-SMD surface-mount package.

Feature Summary

• High insulation voltage capability for safe signal transmission across isolated circuits
• NPN phototransistor output configuration for standard logic interfacing
• Surface-mount design suitable for automated assembly processes

Applications

• General purpose signal isolation in industrial control systems
• Interface between microcontrollers and high-voltage switching circuits
• Power supply feedback loop isolation

Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm the exact current transfer ratio binning and packaging type. Ensure that the procurement source provides valid traceability and authenticity certificates matching the manufacturer's specifications. Cross-reference the datasheet revision date to confirm compliance with current environmental regulations such as RoHS standards before finalizing orders.

Selection Notes

Select this component when a single-channel isolation barrier with moderate speed requirements is needed. The 4-SMD package offers space efficiency compared to through-hole alternatives. Consider the specific CTR range required for the application to ensure proper drive conditions are met without exceeding maximum ratings. Evaluate thermal management needs based on the specified power dissipation limits in the operating environment.

Part Context

This part belongs to the SFH615A series of high-reliability optocouplers designed for robust performance in demanding environments. The series utilizes advanced semiconductor technology to maintain consistent optical coupling characteristics over time. It serves as a critical interface component in systems requiring galvanic separation between low-voltage control logic and higher-voltage power stages.

Replacement Considerations

Direct replacements must match the 4-SMD footprint, 5300 Vrms isolation rating, and NPN output type. Verify that alternative components offer comparable current transfer ratios and switching times to maintain circuit timing integrity. Check for pinout compatibility to avoid PCB redesign efforts during substitution.
