Overview
The SFH6206-1 is a single-channel phototransistor output optocoupler in an SMD-4 package. It features a high current transfer ratio of 40% to 125%. The device supports a maximum forward current of 60 mA with a typical forward voltage of 1.65 V. Isolation voltage is rated at 5300 Vrms. Output parameters include a collector-emitter voltage of 70 V, collector current of 100 mA, and saturation voltage of 400 mV. Switching times are typically 2 µs for both rise and fall. Power dissipation is 250 mW, operating from -55°C to +100°C.
Feature Summary
- High current transfer ratio for efficient signal transmission
- Low coupling capacitance for noise immunity
- High isolation voltage rating
- AC input capability
Applications
- AC mains switching applications
- Solid-state relays
- Industrial control systems
- Power supply feedback loops
Procurement Notes
Verify the specific suffix '1' corresponds to the 40-125% CTR range. Confirm RoHS compliance status via official documentation. Check lead times as they may vary by distributor. Ensure the SMD-4 package matches PCB footprint requirements. Validate temperature ratings against operational environment constraints.
Selection Notes
Select this component when high CTR and AC input compatibility are required. The SMD-4 package suits space-constrained designs. Verify isolation voltage meets safety standards. Consider switching speed if high-frequency operation is needed. Compare CTR ranges with other variants like SFH6206-2 or -3 for tighter tolerance needs.
Part Context
Part of the Vishay SFH6206 series, designed for surface mount assembly. Offers robust isolation and high CTR. Commonly used in industrial and power electronics. Competes with similar AC-input optocouplers. Provides reliable performance in noisy environments.
Replacement Considerations
SFH6206-2 (CTR 100-300%) and SFH6206-3 (CTR 100-600%) offer higher gain. SFH6206-1T is the tape-and-reel version of SFH6206-1. DIP alternatives exist but require layout changes.
FAQ
What is the input type for SFH6206-1?
The SFH6206-1 accepts both AC and DC input signals.
What is the isolation voltage rating?
