Overview
The SFH618A-5X007 is a single-channel transistor output optocoupler from Vishay. It features an NPN phototransistor output with a high current transfer ratio of 250% to 500% at 1mA forward current. The device provides robust isolation with a rated voltage of 5300Vrms. Electrical characteristics include a maximum collector-emitter voltage of 55V, a collector current of 50mA, and a typical rise/fall time of 3.5µs/5µs. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation voltage rating of 5300Vrms for reliable signal transmission across isolated circuits
- Wide current transfer ratio range of 250% to 500% ensures consistent performance at low input currents
- Fast switching speed with typical rise and fall times of 3.5µs and 5µs respectively
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in measurement and testing equipment
- Power supply feedback loops for voltage regulation
- General purpose digital signal isolation interfaces
Procurement Notes
Verify the specific suffix '5X007' to confirm the required current transfer ratio bin (250%-500%) and package type. Ensure the procurement order matches the exact Vishay part number to avoid receiving variants with different CTR ranges or packaging formats. Cross-reference the datasheet for the latest revision status before finalizing component selection.
Selection Notes
Select this component when high isolation voltage and wide CTR tolerance are critical. The 4-SMD package suits surface mount applications. Consider the 50mA collector current limit for load driving capabilities. Verify thermal management requirements given the operating temperature range up to 100°C. Compare against other SFH618A variants if different CTR bins or through-hole packages are needed.
Part Context
This device belongs to the SFH618A series of Vishay's transistor output optocouplers. The series offers various CTR bins and packaging options to suit different design constraints. The SFH618A-5X007 specifically targets applications needing high isolation and precise gain characteristics in a compact surface-mount footprint.
Replacement Considerations
SFH618A-5X007T is a tape-and-reel version of the same electrical specification. SFH618A-4X016 offers a lower CTR range (160%-320%). SFH618A-2 provides a significantly lower CTR (63%-125%). Verify pinout compatibility and CTR requirements when substituting.
