Overview
The SFH601-3X019T is a single-channel optocoupler featuring an infrared LED and an NPN phototransistor with base output in a surface-mount SMD-6 package. It provides electrical isolation with a rated insulation voltage of 5000 Vrms. The device supports a maximum forward current of 60 mA and a collector current of 50 mA, with a collector-emitter voltage rating of 100 V. The current transfer ratio ranges from 100% to 200%. Operating temperatures span from -55°C to +100°C.
Feature Summary
- Integrates an infrared LED emitter with an NPN phototransistor for efficient electro-optical conversion
- Provides high-voltage electrical isolation between input and output circuits via a fixed internal gap
- Includes a base terminal on the phototransistor to facilitate faster switching speeds and improved linearity
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical isolation between distinct circuit sections or systems
- Impedance transformation in isolated interfaces
Procurement Notes
Verify the specific suffix X019T confirms the surface-mount SMD-6 packaging variant rather than the through-hole DIP version. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding manufacturing site transfers or material updates before finalizing procurement orders.
Selection Notes
Select this component when surface-mount assembly is required for single-channel isolation applications. Ensure the design accommodates the 5000 Vrms isolation rating and the 100V collector-emitter voltage limit. Verify that the 60mA forward current capability aligns with the driving circuit constraints and thermal management requirements.
Part Context
This part belongs to the Vishay SFH601 series of transistor-output optocouplers. It shares core electrical characteristics with other variants like the SFH601-3 but differs in physical packaging. The series is designed for general-purpose isolation tasks requiring reliable signal transfer across electrically separated domains.
Replacement Considerations
Direct substitutes include the SFH601-3X009T which offers identical electrical specifications in a similar surface-mount configuration. Cross-reference pinout compatibility and thermal dissipation characteristics when evaluating alternative suppliers or package variations within the same product family.
