SFH620A-1XSMT&R

Overview

The SFH620A-1XSMT&R is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features an AC input configuration utilizing inverse parallel infrared LEDs and an NPN silicon phototransistor output. The device provides high isolation voltage of 5300Vrms and operates within a temperature range of -40°C to 100°C. Packaged in a 4-SMD surface-mount format, it supports a maximum forward current of 50 mA and offers a minimum current transfer ratio of 100%.

Feature Summary

AC input capability enabled by inverse parallel infrared LED structure
High voltage isolation for safe signal transmission between circuits
NPN silicon phototransistor output for reliable switching performance

Applications

Logic-to-logic isolation in noisy environments
Line receiver circuits
Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix '1XSMT&R' against official Isocom documentation to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with AC input requirements, as this model differs from DC-input variants. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components and confirm current production status.

Selection Notes

Select this component when AC input driving is required without external rectification circuitry. The 4-SMD package suits space-constrained surface-mount designs. Verify that the 5300Vrms isolation rating meets system safety standards. Confirm that the NPN transistor output characteristics align with the load requirements of the receiving circuit.

Part Context

This part belongs to the SFH620A series of optically coupled isolators. The series typically includes various package options such as DIP and SMD configurations. Isocom Components manufactures these devices as industry-standard replacements for legacy optocouplers, maintaining consistent electrical performance across different form factors.
