Overview
The SFH6325 is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division, featuring dual channels with transistor outputs. It provides 5300 Vrms galvanic isolation between input and output circuits. The device supports data rates up to 1 MBd and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70V, a typical forward voltage of 1.33V, and a current transfer ratio of 16%. It is available in an SMD-8 package.
Feature Summary
- Dual-channel configuration for simultaneous signal isolation
- High-speed operation supporting 1 MBd data transmission
- Robust 5300 Vrms insulation for safe boundary crossing
- TTL compatibility for direct logic interface integration
Applications
- Industrial automation control systems
- Data communication interface isolation
- Power supply feedback loops
- Microcontroller peripheral protection
Procurement Notes
Verify the specific suffix (e.g., X009T) against the required packaging format, as variants exist in cut tape or full reel configurations. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding bond wire diameter or mold compound updates before finalizing procurement orders.
Selection Notes
Select this component when dual-channel isolation at high speeds is required. Ensure the SMD-8 footprint matches the PCB layout constraints. Verify that the 16% current transfer ratio meets the drive requirements of the receiving circuitry under the intended operating temperature conditions.
Part Context
This part belongs to the SFH6325/SFH6326 family of high-speed optocouplers from Vishay. These devices are designed for applications requiring fast signal transmission across isolated barriers. The series offers various packaging options and channel counts to suit different system density and performance needs.
Replacement Considerations
Public confirmed substitutes include the SFH6325-X017T, though it is marked as obsolete. Parametric equivalents may be available from other manufacturers, but pinout and isolation voltage must be verified.
