SFH6156-2X001T

Overview

The SFH6156-2X001T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output with a maximum collector-emitter voltage of 70 V and a collector current rating of 100 mA. The device provides high isolation capability with an insulation voltage of 5300 Vrms. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.65 V, and a power dissipation of 150 mW. The current transfer ratio ranges from 63% to 125%. Switching characteristics specify a rise time of 3 µs and a fall time of 14 µs. The component operates within a temperature range of -55°C to +100°C and is housed in a compact SMD-4 surface-mount package.

Feature Summary

• High reliability design with 5300 Vrms insulation voltage for robust signal isolation
• NPN phototransistor output configured for efficient switching applications
• Surface-mount SMD-4 package optimized for automated PCB assembly processes

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission across isolated ground planes
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix X001T during procurement to confirm the current transfer ratio binning and tape-and-reel packaging format. Cross-reference the manufacturer part number with official Vishay documentation to ensure compliance with RoHS standards and lead frame specifications. Confirm that the ordering code matches the required CTR range of 63-125% for your circuit design constraints.

Selection Notes

Select this component when high isolation voltage and moderate speed are required for DC or low-frequency signal transmission. The NPN output type suits applications needing open-collector configurations. Ensure the input current does not exceed 60 mA and verify that the load can handle the 100 mA maximum collector current. Consider the thermal management requirements given the 150 mW power dissipation limit in the SMD-4 package.

Part Context

This device belongs to the SFH6156 family of high-reliability optocouplers designed for demanding industrial environments. The family offers various current transfer ratio bins and packaging options to suit different application needs. The SFH6156 series is characterized by its small footprint and ability to maintain signal integrity across high-voltage barriers, making it suitable for space-constrained designs requiring reliable electrical separation.

Replacement Considerations

Compatible substitutes within the same family include SFH6156-2T and SFH6156-2X001. Verify that any replacement maintains the identical 5300 Vrms isolation rating and NPN output configuration. Ensure the alternative part supports the same SMD-4 package dimensions and meets the required current transfer ratio specifications for circuit compatibility.
