SFH6206-3T

Overview

The SFH6206-3T is a single-channel surface-mount optocoupler featuring an AC-input LED and NPN phototransistor output. It provides high isolation voltage of 5300 Vrms, suitable for demanding industrial applications. The device supports a maximum forward current of 60 mA with a typical forward voltage of 1.65 V. Current transfer ratio ranges from 100% to 320%. Switching characteristics include typical rise and fall times of 2 µs. It operates within a temperature range of -55°C to +100°C and is housed in a compact 4-SMD package.

Feature Summary

• AC-input capability allows direct connection to AC signals without external rectification
• High isolation voltage ensures robust electrical separation between input and output circuits
• Fast switching speed with typical 2 µs rise and fall times for efficient signal transmission
• Wide operating temperature range supports reliable performance in harsh environments

Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Power supply feedback loops
• Microcontroller interface isolation

Procurement Notes

Verify the specific suffix '3T' corresponds to the required current transfer ratio bin (100%-320%) as defined by Vishay. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to ordering. Ensure packaging format matches production requirements, as options include tape and reel or cut tape. Cross-reference datasheet revisions to confirm parameter consistency.

Selection Notes

Select this component when AC input detection is required without additional rectifying components. The high CTR range accommodates varying load conditions. Verify that the 70 V collector-emitter voltage rating meets circuit requirements. Consider thermal management within the specified -55°C to +100°C operational window. Compare against DC-input variants if AC sensing is not necessary.

Part Context

This part belongs to the Vishay SFH6206 series of transistor-output optocouplers. The series offers various CTR bins and packaging options. The SFH6206-3T specifically denotes the SMD version with AC input compatibility and a defined CTR range. It complements other family members like SFH6106 for DC applications.

Replacement Considerations

SFH6206-3 is the DIP equivalent. SFH6206-2T offers different CTR specifications. Direct pin-compatible replacements require verification of isolation voltage and CTR limits against original design constraints.
