SFH6186-5X001

Overview

The SFH6186-5X001 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output housed in a 4-SMD surface-mount package. The device provides high isolation with an insulation voltage of 5300 Vrms and supports a maximum collector-emitter voltage of 55 V. Key electrical parameters include a forward current of 60 mA, a typical forward voltage of 1.5 V, and a power dissipation of 150 mW. The current transfer ratio ranges from 250% to 500%, with rise and fall times of 3.5 µs and 5 µs respectively. It operates within a temperature range of -55°C to +100°C.

Feature Summary

• High isolation voltage capability for safe signal transmission between isolated circuits
• Fast switching performance suitable for digital communication applications
• Wide operating temperature range for reliable industrial use

Applications

• Industrial control systems requiring galvanic isolation
• Signal isolation in microprocessor-based circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix designation against official Vishay documentation to ensure correct CTR binning and packaging configuration. Confirm that the 4-SMD footprint matches the target PCB design. Check RoHS compliance status as required by project specifications. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to assembly.

Selection Notes

Select this component when high isolation voltage and fast response are critical. Compare current transfer ratio requirements against the 250-500% range. Consider thermal management due to 150 mW power dissipation. Evaluate package compatibility with automated placement equipment. Verify input current limits relative to driving circuit capabilities.

Part Context

This part belongs to the SFH6186 series of transistor output optocouplers. It shares architectural similarities with other variants like SFH6186-3T and SFH6186-4T but differs in current transfer ratio bins and packaging options. The series is designed for general-purpose isolation tasks in electronic equipment.

Replacement Considerations

Direct substitutes may include SFH6186-5 or SFH618A-5X016 if through-hole packaging is acceptable. For SMD replacements, verify pinout compatibility and electrical parameter overlap with SFH6186-5X001T.
