SFH6186-3T

Overview

The SFH6186-3T 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 200%. The device provides a high isolation voltage of 5300 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 55 V, a maximum forward current of 60 mA, and a typical rise time of 3.5 µs. It is housed in a 4-SMD鸥翼 package.

Feature Summary

• High isolation voltage capability of 5300 Vrms for robust circuit separation
• NPN phototransistor output configuration for standard switching applications
• Surface mount SMD-4 package design facilitating automated assembly processes

Applications

• Industrial control systems requiring galvanic isolation
• Signal isolation in measurement and testing equipment
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix 'T' confirms the tape-and-reel packaging format rather than tube packaging when sourcing components. Ensure that the requested quantity aligns with standard reel sizes provided by the manufacturer or authorized distributors. Confirm RoHS compliance status and check for any recent product change notices regarding frame plating or material composition updates before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and moderate speed are required for signal transmission between isolated circuits. The specified current transfer ratio range supports reliable switching with standard LED drive currents. Consider the thermal characteristics and power dissipation limits during layout design to ensure stable operation across the full industrial temperature range without derating issues.
