SFH601-2XSMT&R

Overview

The SFH601-2XSMT&R is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features an infrared LED input and an NPN silicon phototransistor output with a base terminal. The device provides high isolation voltage of 5300Vrms. Key electrical parameters include a maximum DC forward current of 60 mA, collector-emitter saturation voltage of 400mV, and typical switching times of 3µs (on) and 2.3µs (off). The current transfer ratio ranges from 63% to 125% at 10mA input. It operates within a temperature range of -55°C to 100°C and is housed in a surface-mount 6-pin SMPDIP package.

Feature Summary

• Integrates an infrared emitting diode with an NPN silicon phototransistor for signal transmission
• Provides high-voltage electrical isolation between input and output circuits
• Includes a base terminal on the phototransistor for enhanced sensitivity and speed control

Applications

• General-purpose digital signal isolation in industrial control systems
• Interface circuits between microcontrollers and high-voltage loads
• Signal transmission in environments requiring galvanic isolation

Procurement Notes

Verify the manufacturer designation carefully, as this component is associated with both Vishay Semiconductor Opto Division and Isocom Components 2004 LTD due to acquisition history. Confirm the specific suffix 'XSMT&R' corresponds to the required surface-mount tape-and-reel packaging. Check datasheet revisions to ensure parameter consistency, particularly regarding isolation voltage ratings and thermal characteristics, before finalizing procurement specifications.

Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation with a phototransistor output featuring a base pin. The choice is driven by the need for moderate switching speeds and high isolation voltage in compact PCB layouts. Ensure the application current requirements fall within the specified 60mA forward current limit and that the operating temperature range suits the environmental conditions.

Part Context

This part belongs to the SFH601 series of optocouplers, which are designed for general-purpose isolation applications. The series typically includes variants with different packaging options, such as through-hole DIP and surface-mount configurations. The inclusion of a base terminal distinguishes these devices from standard phototransistor outputs, allowing for external biasing or faster response times in specific circuit designs.

Replacement Considerations

Direct replacements may include other single-channel phototransistor optocouplers with similar isolation ratings and surface-mount packages. Verify compatibility of pinout, current transfer ratio, and switching speeds. Note that while Vishay was the original manufacturer, Isocom Components now produces equivalent parts under this branding.
