SFH6186-4

Overview

The SFH6186-4 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and utilizes surface-mount SMD-4 packaging for through-hole installation compatibility. The device provides high isolation with a rated insulation voltage of 5300 Vrms. Key electrical parameters include a current transfer ratio (CTR) ranging from 160% to 320%, a maximum collector-emitter voltage of 55 V, and a maximum collector current of 100 mA. The forward voltage is specified at 1.5 V with a maximum forward current of 60 mA. Switching characteristics include a typical rise time of 3.5 µs and a fall time of 5 µs. The component operates within a temperature range of -55°C to +100°C and has a power dissipation rating of 150 mW.

Feature Summary

High current transfer ratio capability for efficient signal transmission at low input currents
Robust electrical isolation suitable for safety-critical circuit separation
Compact surface-mount package design facilitating automated assembly processes

Applications

Industrial control systems requiring signal isolation

Power supply feedback loops

Procurement Notes

Verify the specific suffix designation to confirm the exact current transfer ratio bin and packaging configuration. Ensure that the procurement documentation aligns with the required isolation voltage standards and operating temperature range for the intended application environment. Cross-reference the manufacturer's latest datasheet for any updates regarding compliance certifications or material composition declarations.

Selection Notes

Select this component when a high current transfer ratio is required to ensure reliable switching performance under varying conditions. Consider the SMD-4 package dimensions for PCB layout constraints. Evaluate the thermal management requirements based on the 150 mW power dissipation limit and the operational temperature range to maintain long-term reliability in the target system.

Part Context

This part belongs to the SFH6186 series of transistor output optocouplers designed for general-purpose isolation applications. The series offers various CTR bins to accommodate different sensitivity requirements. The SFH6186-4 specifically targets applications needing higher gain compared to lower CTR variants within the same family, providing enhanced noise immunity and signal integrity in digital communication interfaces.
