Overview
The SFH6206-1T is a single-channel surface-mount optocoupler featuring an NPN phototransistor output. It provides high isolation with a rated voltage of 5300 Vrms and supports AC input signals. Key electrical parameters include a maximum forward current of 60 mA, a typical forward voltage of 1.65 V, and a collector-emitter saturation voltage of 400 mV. The device exhibits a current transfer ratio ranging from 40% to 125%, with typical rise and fall times of 2 µs each. It operates within a temperature range of -55°C to +100°C.
Feature Summary
- High isolation capability with 5300 Vrms rating for safe signal transmission between isolated circuits.
- AC input compatibility allows direct coupling with alternating current sources without additional rectification.
- Fast switching performance with 2 µs typical rise and fall times suitable for moderate-speed digital applications.
Applications
- Industrial control systems requiring galvanic isolation
- Solid-state relay driver circuits
- Microcontroller interface isolation
Procurement Notes
Verify the specific suffix '1T' against the official Vishay datasheet to confirm the exact Current Transfer Ratio (CTR) binning, as other variants in the SFH6206 series may have different CTR specifications. Ensure the ordering part number matches the required package type and tape/reel configuration for automated assembly processes.
Selection Notes
Select this component when AC input detection is required alongside high-voltage isolation. Compare the 40-125% CTR range against system gain requirements. Consider the 60 mA maximum forward current limit for input drive circuitry design. Verify that the 70 V collector-emitter voltage rating exceeds the load voltage in the target application.
Part Context
This device belongs to the Vishay SFH6206 series of transistor-output optocouplers. The series is designed for general-purpose isolation applications, offering various CTR bins and input types. The SFH6206-1T specifically denotes the variant optimized for AC input applications with a defined CTR range, distinguishing it from DC-input or different CTR versions within the same family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Vishay SFH6206 variants only if CTR and input type specifications align exactly.
