Overview
The Vishay SFH6916-X001 is a quad-channel surface-mount optocoupler in a 16-pin SSOP package. It features GaAs infrared emitters coupled to silicon planar phototransistors. Key electrical parameters include a maximum forward voltage of 1.4V, max input current of 50mA, and isolation voltage of 3750Vrms. The current transfer ratio ranges from 50% to 300%. Typical rise and fall times are 4μs and 3μs respectively. Operating temperature spans -55°C to +100°C.
Feature Summary
- Quad-channel configuration for multi-signal isolation
- High isolation voltage capability
- Logic output compatibility
- Wide operating temperature range
Applications
- Industrial control systems
- Communication equipment signal isolation
- Microprocessor interface circuits
Procurement Notes
Verify the specific suffix X001 against official Vishay documentation to confirm pinout and packaging details. Ensure compliance with UL, EN, and CSA standards required for your application. Cross-reference datasheet revisions to confirm parameter stability. Confirm RoHS status if environmental regulations apply. Validate supplier authenticity due to market availability variations.
Selection Notes
Select this component when four isolated channels are required in a compact surface-mount form factor. The high CTR range supports robust signal transmission. Ensure input current limits are respected to maintain longevity. Verify thermal management requirements within the specified temperature range. Consider package dimensions for PCB layout constraints.
Part Context
Part of the Vishay SFH series, designed for general-purpose isolation. The SFH6916 variant specifically offers quad-channel integration. It utilizes standard phototransistor output technology. The series is recognized for reliability in industrial environments. Competitors offer similar quad-channel options with varying isolation ratings.
Replacement Considerations
Check for direct equivalents like the SFH6916 without suffix if packaging matches. Verify pin-to-pin compatibility before substitution. Ensure replacement parts meet the same 3750Vrms isolation requirement. Confirm identical channel count and output type.
