Overview
The SFH6186-3 is a single-channel transistor output optocoupler from Vishay. It features an NPN phototransistor output with a current transfer ratio (CTR) of 100% to 200%. Key electrical parameters include a maximum collector-emitter voltage of 55 V, a maximum collector current of 100 mA, and an isolation voltage of 5300 Vrms. The device operates within a temperature range of -55°C to +100°C, has a typical rise time of 3.5 µs and fall time of 5 µs, and dissipates up to 150 mW.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Delivers fast switching performance suitable for signal transmission
- Offers wide operating temperature range for industrial environments
Applications
- Industrial automation control systems
- Consumer electronics signal isolation
- Power supply feedback loops
Procurement Notes
Verify the specific suffix matches the required CTR bin (100-200%) and packaging type (tube or tape/reel). Confirm RoHS compliance status and check for any recent PCN updates regarding frame plating or material changes. Ensure the ordering code aligns with the desired moisture sensitivity level and shipping configuration.
Selection Notes
Select this component when high isolation voltage and moderate speed are required. The SFH6186-3 is suitable for applications needing reliable galvanic isolation in noisy environments. Consider the CTR tolerance if precise gain control is necessary. Compare against other SFH6186 variants if different isolation ratings or CTR ranges are needed.
Part Context
This part belongs to the SFH6186 series of transistor output optocouplers designed for general-purpose isolation. It shares the same physical package and basic electrical characteristics with other variants like the SFH6186-2, -4, and -5, which differ primarily in their Current Transfer Ratio bins and isolation voltage ratings.
Replacement Considerations
Direct substitutes include other SFH6186 variants such as SFH6186-2, SFH6186-4, or SFH6186-5, provided the CTR and isolation voltage requirements are met. Verify pinout compatibility and thermal characteristics before substitution.
