Overview
The SFH6206-2T is a single-channel phototransistor output optocoupler designed for surface mount applications. It features an AC input LED and provides high isolation voltage of 5300 Vrms. The device supports a maximum forward current of 60 mA with a typical forward voltage of 1.65 V. Key electrical parameters include a collector-emitter saturation voltage of 400 mV, a collector current rating of 100 mA, and a peak collector-emitter voltage of 70 V. The current transfer ratio ranges from 63% to 200%. Typical switching times are 2 µs for both rise and fall durations.
Feature Summary
- AC input capability allows direct connection to alternating current sources without external rectification.
Applications
- Solid-state relay driver circuits
- Mains voltage detection interfaces
- Industrial control system isolation
Procurement Notes
Verify the specific suffix '2T' corresponds to the required Current Transfer Ratio binning, as Vishay utilizes alphanumeric codes to denote CTR performance tiers. Confirm that the 4-SMD package dimensions align with the target PCB footprint. Ensure compliance with RoHS directives if applicable to the end product requirements.
Selection Notes
Select this component when AC signal isolation is required within a compact surface-mount form factor. The high CTR range accommodates varying load conditions, while the robust isolation voltage ensures safety in mains-connected environments. Evaluate thermal dissipation capabilities against the 250 mW power rating during continuous operation.
Part Context
This part belongs to the Vishay SFH6206 series, which specializes in AC-input optocouplers. The series offers various CTR bins and packaging options to suit different isolation needs. The SFH6206-2T specifically targets applications requiring reliable AC sensing with standard transistor output characteristics.
Replacement Considerations
Cross-reference with SFH6206-3T or SFH6206-1T for alternative CTR specifications. Verify pinout compatibility and isolation voltage ratings before substituting with other AC-input optocouplers.
