SFH615A-3X009

Overview

The SFH615A-3X009 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output housed in a 4-SMD,鸥翼 (gull-wing) surface-mount package. The device provides high isolation with a rated insulation voltage of 5300 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70 V and a continuous collector current of 50 mA. The forward current rating is 60 mA, with a typical forward voltage of 1.35 V. The current transfer ratio ranges from 100% to 200% at a forward current of 10 mA. Switching characteristics include a rise time of 2 µs and a fall time of 2 µs. The unit operates within a temperature range of -55°C to +100°C.

Feature Summary

• Provides galvanic isolation between electrically separated circuits using infrared LED and NPN phototransistor technology.
• Designed for end-stackable mounting with standard 2.54 mm lead spacing compatibility in surface-mount configurations.
• Offers high reliability performance suitable for signal transmission applications requiring robust electrical separation.

Applications

• Signal transmission between isolated circuit sections
• General-purpose digital signal isolation
• Interface circuits requiring high isolation voltage

Procurement Notes

Verify the specific suffix X009 corresponds to the 4-SMD gull-wing package configuration rather than through-hole variants like VO615A-3. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the supplier documentation explicitly lists the 5300 Vrms isolation rating and the 100-200% CTR range for quality assurance purposes.

Selection Notes

Select this component when a surface-mount solution is required for high-isolation applications. Compare switching speeds and package dimensions against alternatives if board space is constrained. Verify that the 70 V collector-emitter voltage meets the load requirements. Consider the 1.35 V forward voltage drop for drive circuit design. Ensure thermal management supports the specified operating temperature range.

Part Context

This part belongs to the SFH615A series of transistor output optocouplers. It serves as a surface-mount alternative to through-hole devices such as the VO615A-3 and SFH615A-3. The series is characterized by high isolation voltage and standard current transfer ratios. Vishay designs these components for reliable signal coupling in industrial and consumer electronics environments.

Replacement Considerations

The VO615A-3 is listed as a recommended alternative but utilizes a DIP-4 through-hole package. Direct pin-to-pin replacement requires verifying package compatibility. Other SFH615A variants may share electrical characteristics but differ in packaging or tape-and-reel specifications.
