Overview
The SFH608-5 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor with base connection and utilizes a 6-DIP (PDIP-6) through-hole package. The device provides an isolation voltage of 5300 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 55 V, a maximum collector current of 50 mA, and a forward current of 50 mA. The typical current transfer ratio ranges from 100% to 200%. 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 speed optimization.
- Provides high-voltage isolation capability suitable for demanding industrial and safety-critical applications.
- Designed for through-hole mounting in standard 6-pin DIP packages for reliable PCB integration.
Applications
- Industrial automation systems requiring galvanic isolation
- Solid-state relay driver circuits
- Microcontroller interface isolation
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific binning requirements for current transfer ratio prior to procurement. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet to maintain performance integrity upon installation.
Selection Notes
Select this component when base-controlled phototransistor functionality is required for faster switching speeds compared to standard variants. Evaluate the 5300 Vrms isolation rating against system safety standards. Consider the 6-DIP package constraints for board space and verify thermal dissipation capabilities within the specified operating temperature range.
Part Context
This part belongs to the SFH608 series of low input current optocouplers. It shares the same physical footprint and basic isolation characteristics as other variants in the family but differs in current transfer ratio specifications and internal phototransistor configuration. The series is designed for general-purpose isolation tasks in electronic circuits.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameter overlaps with potential alternatives before substitution.
