SFH6206-3

Overview

The SFH6206-3 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a current transfer ratio ranging from 100% to 320%. The device provides high isolation voltage of 5300 Vrms and supports a maximum forward current of 60 mA. Key electrical parameters include a typical forward voltage of 1.25 V, maximum collector-emitter saturation voltage of 400 mV, and rise/fall times of 2 µs. It operates within a temperature range of -55°C to +100°C.

Feature Summary

• High isolation voltage capability for robust circuit protection
• Fast switching performance with low propagation delay
• Wide operating temperature range for diverse environmental conditions

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops
• Communication interface isolation

Procurement Notes

Verify the specific suffix designation (e.g., -T or -X001T) against the required packaging format, as standard tube packaging differs from tape and reel options. Confirm RoHS compliance status and ensure the selected variant matches the intended surface-mount assembly process requirements.

Selection Notes

Select this component when high isolation voltage and fast response are critical. Ensure the CTR range meets the drive requirements of the receiving circuit. Consider thermal management within the specified operating temperature limits and verify pin compatibility with the target PCB footprint.

Part Context
