Overview
The SFH600-3XSMT&R is a surface-mount optocoupler from Isocom Components, featuring a single channel with an NPN phototransistor output. It provides high isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to +100°C. The device supports a maximum forward current of 60 mA and has a typical rise time of 4 µs. Current transfer ratio ranges from 160% to 320%. It is housed in a compact SMD package suitable for automated assembly.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- NPN phototransistor output configuration for reliable switching applications
- Wide operating temperature range ensuring stability in harsh environments
- Surface-mount packaging design facilitating automated PCB assembly
Applications
- Industrial control systems requiring galvanic isolation
- Power supply units needing feedback loop isolation
- Solid-state relay drivers for AC load switching
- Microcontroller interface circuits for noise immunity
Procurement Notes
Verify the exact suffix 'XSMT&R' against official Isocom documentation to confirm specific tape-and-reel specifications and lead frame plating. Ensure compatibility with standard reflow soldering profiles for surface-mount devices. Cross-reference with authorized distributors for genuine component sourcing to avoid counterfeit parts.
Selection Notes
Select this component when high CTR and robust isolation are required in a small footprint. Compare with through-hole equivalents if mechanical stress resistance is critical. Consider thermal management requirements given the power dissipation limits. Verify input current capabilities match the driving circuit constraints.
Part Context
This part belongs to the SFH600 series of optocouplers manufactured by Isocom Components. The series is known for replacing obsolete Vishay Semiconductors parts. It offers similar pinouts and electrical characteristics to industry-standard DIP-6 packages but adapted for surface-mount technology.
Replacement Considerations
Direct replacements include SFH600-3G (through-hole) or SFH600-4G with adjusted CTR specifications. Verify pinout compatibility before substitution. Check isolation voltage ratings to ensure they meet or exceed original design requirements.
