Overview
The SFH6186-5T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a high current transfer ratio ranging from 250% to 500%. The device provides robust electrical isolation with a rated insulation voltage of 5300 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 55 V, a maximum collector current of 100 mA, and a forward current of 60 mA. Typical switching characteristics consist of a 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 is housed in a 4-SMD gull-wing package.
Feature Summary
- High current transfer ratio for efficient signal transmission
- High isolation voltage ensuring safe circuit separation
- Fast switching speeds suitable for digital applications
Applications
- General purpose digital signal isolation
- Microcontroller interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix '5T' corresponds to the required CTR bin (250-500%) and SMD packaging configuration. Confirm that the 5300 Vrms isolation rating meets system safety requirements. Ensure the operating temperature range aligns with the final application environment. Cross-reference the datasheet for any recent PCN updates regarding material or manufacturing changes.
Selection Notes
Select this component when high CTR and fast response are critical for single-channel isolation. Compare against SFH6186-3T if lower CTR suffices, or SFH6186-4T for through-hole mounting. Consider the 4-SMD footprint constraints during PCB layout. Evaluate power dissipation limits under continuous operation conditions to ensure thermal stability within the specified junction temperature range.
Part Context
This part belongs to the SFH618 series of transistor output optocouplers. The series offers various CTR bins and packaging options to suit different design needs. The SFH6186 variant specifically targets applications requiring higher isolation voltages and faster switching compared to standard low-speed isolators. It complements other Vishay optocouplers like the SFH618A for DIP packages.
Replacement Considerations
SFH6186-3T offers similar form factor but lower CTR (100-200%). SFH6186-4T provides identical electrical performance but uses through-hole packaging instead of surface mount.
