SFH610A-2X006

Overview

The SFH610A-2X006 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and utilizes a DIP-4 through-hole package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 100 mA, and a forward current of 60 mA. The device offers a high isolation voltage of 5300 Vrms and a typical forward voltage of 1.65 V. Current transfer ratio ranges from 63% to 125%, with rise and fall times of 3 µs and 14 µs respectively. Power dissipation is rated at 150 mW, operating within a temperature range of -55°C to +100°C.

Feature Summary

• High isolation voltage capability for safe signal transmission across potential barriers
• NPN phototransistor output configuration suitable for digital switching applications
• Through-hole DIP-4 packaging designed for robust mechanical mounting

Applications

• General purpose signal isolation in industrial control systems
• Interface between microcontrollers and high-voltage circuits
• Power supply feedback loop isolation

Procurement Notes

Verify the specific suffix X006 against the manufacturer datasheet to confirm tube packaging details and binning specifications. Ensure compatibility with existing PCB footprints for DIP-4 packages. Cross-reference recommended alternatives such as VO610A-2 if supply constraints exist. Confirm RoHS compliance status through official documentation before integration into regulated products.

Selection Notes

Select this component when high isolation voltage and moderate speed are required for DC input applications. The NPN output type suits direct interfacing with logic inputs. Evaluate thermal management requirements given the 150 mW power dissipation limit. Consider the 5300 Vrms insulation rating for safety-critical designs requiring reinforced isolation barriers between primary and secondary sides.

Part Context

The SFH610A series represents Vishay's line of high-reliability optocouplers featuring high current transfer ratios and low coupling capacitance. This specific model belongs to the DIP variant family, distinguished from surface-mount options like the SFH6106. The series is engineered for applications demanding robust galvanic isolation with stable performance over extended temperature ranges.

Replacement Considerations

VO610A-2 is listed as a recommended alternative with similar electrical characteristics and pinout compatibility.
