SFH601-3X009

Overview

The SFH601-3X009 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor with a base connection, housed in a surface-mount 6-SMD package. The device provides 5000 Vrms insulation voltage and supports a maximum forward current of 60 mA with a forward voltage of 1.65 V. Key electrical parameters include a collector-emitter saturation voltage of 400 mV, a reverse voltage of 6 V, and power dissipation of 150 mW. The current transfer ratio ranges from 100% to 200%, with a maximum collector current of 50 mA and a collector-emitter voltage rating of 100 V. Operating temperatures span from -55°C to +100°C.

Feature Summary

• Integrates an NPN phototransistor with a dedicated base terminal for enhanced switching control and faster response times.
• Provides high-voltage isolation capability rated at 5000 Vrms between input and output circuits.
• Designed for surface-mount assembly using a compact 6-SMD footprint to facilitate automated PCB placement.

Applications

• Signal isolation in industrial automation control systems
• Interface circuits for microcontrollers requiring galvanic separation
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix X009 confirms the surface-mount 6-SMD configuration and base-connected phototransistor variant. Ensure the procurement documentation explicitly states the 100-200% CTR range and 5000 Vrms isolation rating. Confirm RoHS compliance status through the manufacturer's official declaration. Cross-reference the Vishay datasheet to validate the operating temperature range and package dimensions against your design requirements.

Selection Notes

Select this component when a surface-mount solution with a base-connected phototransistor is required for improved switching speed compared to standard variants. The 5000 Vrms isolation rating suits applications demanding robust galvanic separation. Verify that the 50 mA maximum collector current meets the load requirements. Consider the 6-SMD package constraints for PCB layout density and thermal management capabilities within the specified temperature range.

Part Context
