Overview
The SFH6106-5T is a single-channel surface-mount phototransistor optocoupler from Vishay. It provides electrical isolation with a rated insulation voltage of 5300 Vrms. The device features an NPN phototransistor output capable of handling a maximum collector current of 100 mA and a collector-emitter voltage of 70 V. Key performance parameters include a typical rise time of 4 μs and a fall time of 15 μs. The current transfer ratio ranges from 250% to 500%. It operates within a temperature range of -55°C to +100°C and is supplied in tape and reel packaging.
Feature Summary
- High current transfer ratio for efficient signal transmission
- Low coupling capacitance to minimize interference
- High isolation voltage ensuring robust safety barriers
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in communication interfaces
- Power supply feedback loops
Procurement Notes
Verify the specific suffix '5T' corresponds to the required Current Transfer Ratio (CTR) bin of 250% to 500%, as other suffixes like '3X001' or '4T' indicate different CTR ranges. Confirm that the tape and reel packaging matches your automated assembly equipment specifications. Ensure the 4-SMD package dimensions align with your PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when high-speed switching is not critical but high gain is required, given its 4 μs rise time. Choose the SFH6106-5T over lower CTR variants if driving loads requires higher output current efficiency. Verify that the 70 V collector-emitter voltage rating exceeds the maximum load voltage in the application circuit to prevent breakdown during operation.
Part Context
The SFH6106 belongs to Vishay's SFH series of surface-mount optocouplers designed for compact electronic designs. This family offers various CTR bins and packaging options to suit different manufacturing needs. The SFH6106-5T specifically targets applications needing high isolation and strong signal coupling in a small form factor, distinguishing it from through-hole DIP alternatives in the same product line.
Replacement Considerations
SFH6106-3X001: Offers a lower CTR range of 100% to 200%. SFH6106-4T: Provides a CTR range of 160% to 320%. SFH6186-5T: Features faster switching times (3.5 μs rise, 5 μs fall) but has a lower collector-emitter voltage rating of 55 V.
