SFH601-2SM

Overview

The SFH601-2SM is a surface-mount transistor output optocoupler from the Isocom Components (formerly Vishay) SFH601 series. It features a single channel with an NPN phototransistor output in a DIP-6 compatible SMD package. Key electrical parameters include a maximum isolation voltage of 5300 Vrms, a collector-emitter breakdown voltage of 100 V, and a forward current rating of 60 mA. The typical current transfer ratio ranges from 63% to 125%, with a maximum forward voltage of 1.65 V. Operating temperatures span from -55°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits via optical coupling.
• Features a compact surface-mount design suitable for automated assembly processes.
• Utilizes an NPN phototransistor output for standard logic interface compatibility.

Applications

• Industrial control systems requiring signal isolation
• Computer peripheral interface circuits
• Power supply feedback loops

Procurement Notes

Verify that the specific suffix 'SM' denotes the correct surface-mount tape-and-reel packaging variant required for your manufacturing process. Confirm that the manufacturer designation aligns with Isocom Components or authorized distributors, as historical data may reference Vishay Semiconductors. Ensure compliance with RoHS directives if applicable to your region. Cross-reference the datasheet revision date to confirm parameter stability before finalizing procurement orders.

Selection Notes

Select this component when a robust, general-purpose optocoupler with high isolation voltage is needed for space-constrained PCB layouts. The SFH601-2SM offers a balance of speed and reliability suitable for digital signal transmission. Consider the CTR range of 63-125% to ensure adequate drive capability for downstream logic gates. Evaluate thermal management requirements given the 100°C maximum operating temperature limit.

Part Context

This device belongs to the SFH601 family of optocouplers, widely recognized for their reliability in industrial applications. Originally developed by Vishay Semiconductors, these components are now often associated with Isocom Components. The SFH601-2SM specifically adapts the through-hole SFH601-2 specifications into a surface-mount form factor, maintaining equivalent electrical performance while enabling modern SMT production techniques.
