Overview
The SFH601-2 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a base connection, housed in a DIP-6 through-hole package. The device provides an isolation test voltage of 5000 Vrms and supports a maximum collector-emitter voltage of 100 V. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.65 V, and a collector current rating of 50 mA. The current transfer ratio (CTR) ranges from 63% to 125%. It operates within a temperature range of -55°C to +100°C and has a power dissipation of 150 mW.
Feature Summary
- Integrated base connection on the phototransistor for enhanced switching speed control
- High insulation voltage capability suitable for demanding isolation applications
- Through-hole DIP-6 packaging for standard PCB mounting
Applications
- General purpose signal isolation in industrial control systems
- Switching power supply feedback loops
- Microcontroller input/output isolation
Procurement Notes
Verify the specific suffix code against the manufacturer's latest datasheet to confirm the exact Current Transfer Ratio (CTR) bin, as variants exist within the SFH601 family. Ensure the DIP-6 package type matches your board layout requirements. Confirm RoHS compliance status directly with the supplier documentation prior to procurement.
Selection Notes
Select this component when a phototransistor output with a base terminal is required for faster response times compared to standard versions. The 5000 Vrms isolation rating makes it suitable for high-voltage noise environments. Consider the 63-125% CTR range for gain stability needs. Compare against SFH601-1 or SFH601-3 if different CTR bins are preferred.
Part Context
The SFH601 series comprises single-channel optocouplers with phototransistor outputs. The SFH601-2 specifically denotes the variant with a CTR range of 63% to 125%. Other variants include SFH601-1 (40-80% CTR) and SFH601-3 (100-200% CTR). All share similar electrical characteristics except for the CTR binning and specific ordering suffixes.
Replacement Considerations
Direct replacements within the same family include SFH601-1 and SFH601-3, provided the CTR difference is acceptable for the application. Cross-brand equivalents should be verified for pin compatibility, isolation voltage, and package dimensions.
