Overview
The SFH1617A-3 is a single-channel, through-hole phototransistor output optocoupler from Vishay. It features a GaAsP infrared LED and an NPN phototransistor in a 4-DIP package. Key electrical parameters include a maximum forward current of 60 mA, a typical forward voltage of 1.65 V, and a collector-emitter saturation voltage of up to 400 mV. The device offers a high isolation voltage of 5000 VRMS and a wide operating temperature range from -55°C to +110°C. Typical switching times are 3 μs for rise and 14 μs for fall.
Feature Summary
- Provides galvanic isolation between input and output circuits using an infrared LED and phototransistor pair.
- Features a standard 4-pin DIP package suitable for through-hole mounting applications.
- Designed for high reliability with a specified isolation test voltage of 5000 VRMS.
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix against the manufacturer's latest documentation to confirm pinout and mechanical dimensions. Ensure that the selected component meets the required isolation voltage standards for your application safety regulations. Cross-reference the CTR specifications with system requirements to guarantee adequate signal transfer under varying temperature conditions.
Selection Notes
Select this component when a robust through-hole solution with high isolation voltage is required. Compare the CTR range and switching speeds against alternative models like the SFH1617A-2 if tighter timing constraints exist. Consider the thermal management capabilities within the -55°C to +110°C operating range for harsh environments.
Part Context
This part belongs to the SFH series of optocouplers, which are designed for general-purpose isolation tasks. The SFH1617A-3 specifically utilizes a standard DIP-4 configuration, distinguishing it from surface-mount variants in the same family. It serves as a discrete isolation component for digital and analog signal transmission.
Replacement Considerations
The VO617A-3X016 is listed as a recommended alternative with similar specifications. Verify pin compatibility and exact CTR ranges before substitution. Other SFH1617 variants may differ in packaging or electrical tolerances.
