SFH620A-2X007

Overview

The SFH620A-2X007 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and supports both AC and DC input types. The device provides high isolation with a voltage rating of 5300 Vrms. 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 typical current transfer ratio ranges from 63% to 200%. The component operates within a temperature range of -55°C to +100°C and is housed in a surface-mount 4-pin package.

Feature Summary

• Provides galvanic isolation between input and output circuits using infrared LED and phototransistor technology.
• Supports both AC and DC input signal types for versatile application compatibility.
• Features high insulation voltage capability to ensure safety in high-voltage environments.

Applications

• Digital logic signal transmission and conversion
• Power supply control and switching circuits
• Electrical insulation isolation between circuits and systems

Procurement Notes

Verify the specific suffix X007 to confirm the surface-mount package variant and tape-and-reel packaging configuration. Ensure the selected part matches the required current transfer ratio bin (63%-200%) for your circuit design. Cross-reference the manufacturer part number with official Vishay documentation to confirm RoHS compliance status and lead time availability before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and support for AC/DC inputs are required. The NPN phototransistor output is suitable for standard logic interfacing. Consider the 70V collector-emitter voltage limit and 100mA current capacity for load requirements. Verify that the surface-mount footprint fits the PCB layout constraints compared to through-hole alternatives in the same series.

Part Context

This component belongs to the SFH620A series of transistor output optocouplers. It shares core specifications with variants like SFH620A-2 but differs in packaging and binning. The series is designed for general-purpose isolation applications requiring reliable signal transfer across isolated boundaries while maintaining compact form factors suitable for modern electronic assemblies.

Replacement Considerations

Direct substitutes include other Vishay SFH620A series parts with matching CTR bins, such as SFH620A-2X007T if reel quantity differences exist. Ensure replacement parts maintain the 5300 Vrms isolation rating and compatible pinout configurations. Verify that any alternative maintains the same NPN output type and operating temperature range for equivalent performance.
