SFH620A-1SM

Overview

The SFH620A-1SM is a single-channel optoisolator featuring inverse parallel infrared LEDs and NPN silicon phototransistors. It operates with AC input and provides transistor output isolation. The device supports a maximum output voltage of 70V and an output current of 50mA per channel. It includes Vce saturation support and functions reliably within a temperature range of -30°C to 100°C. The component utilizes a 4-SMD Gull Wing package.

Feature Summary

Features inverse parallel infrared light emitting diodes for AC input compatibility
Utilizes NPN silicon phototransistor output for signal isolation
Provides high voltage isolation between input and output circuits

Applications

Logic-to-logic isolators in noisy environments
Line receiver applications
Computer and peripheral device interfaces

Procurement Notes

Verify the specific suffix '1SM' against official Isocom documentation to confirm the 4-SMD Gull Wing package configuration. Ensure that the AC input requirement aligns with the inverse parallel LED structure. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity, as generic listings may not reflect the exact package variant.

Selection Notes

Select this component when AC input driving is required for the optocoupler circuit. The inverse parallel LED design eliminates the need for external rectification components on the input side. Verify that the 70V output voltage rating and 50mA current capacity meet the load requirements of the isolated side. Confirm that the SMD package type fits the PCB layout constraints.

Part Context

The SFH620A series consists of optically coupled isolators designed for general-purpose isolation tasks. This series combines infrared emission with silicon phototransistor reception. The SFH620A-1SM represents the surface-mount variant of this family, maintaining the electrical characteristics of the broader series while adapting to automated assembly processes.
