SFH6916T

Overview

The SFH6916T is a quad transistor output optocoupler from Vishay Semiconductors, housed in an SSOP-16 surface-mount package. It features four independent channels with NPN phototransistor outputs. Key electrical parameters include a maximum collector-emitter voltage of 70 V and a peak forward current of 50 mA. The device offers a wide current transfer ratio range of 50% to 300%. Isolation voltage is rated at 3750 Vrms. Operating temperatures span from -55°C to +100°C, with a power dissipation capacity of 250 mW.

Feature Summary

• Integrates four independent GaAs infrared emitters coupled to silicon planar phototransistors for multi-channel signal isolation.
• Provides high insulation capability with a 3750 Vrms isolation voltage rating between input and output circuits.
• Supports wide operating temperature ranges suitable for demanding industrial environments.

Applications

• Industrial process control systems requiring multi-channel isolation
• Data communication interfaces needing galvanic separation
• Power supply feedback loops for signal monitoring

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the SSOP-16 footprint matches your PCB design constraints. Ensure thermal management strategies account for the 250 mW power dissipation limit under continuous operation conditions.

Selection Notes

Choose this component when multiple isolated channels are required within a single compact package. The wide CTR range accommodates varying input drive requirements. Consider the 70 V collector voltage limit for load compatibility. Verify that the 50 mA forward current rating aligns with your LED drive circuit capabilities.

Part Context

This part belongs to the SFH6916 series of quad optocouplers. It shares architectural similarities with other Vishay quad devices but distinguishes itself through specific pinout configurations and packaging options. The series targets applications requiring dense integration of isolated signals in space-constrained designs.

Replacement Considerations

Direct substitutes may include other quad optocouplers from Vishay or competitors offering similar SSOP-16 packages. Verify pin-to-pin compatibility and ensure equivalent isolation voltages and current transfer ratios before substitution.
