SFH6319-X001T

Overview

The SFH6319-X001T is a high-speed photodarlington optoisolator manufactured by Vishay Semiconductor Opto Division. It features a single channel with an input voltage of 1.4V and a maximum DC forward current of 1.6mA. The device provides 4000Vrms isolation voltage and supports data rates up to 100kb/s. It operates within a temperature range of -55°C to +100°C and utilizes an 8-SOIC surface-mount package.

Feature Summary

• High gain photodarlington output configuration
• Low input current operation for efficient driving
• Robust 4000Vrms insulation voltage capability
• Surface mount packaging for automated assembly

Applications

• Industrial communication interfaces
• Power supply feedback loops
• General-purpose signal isolation

Procurement Notes

Verify the component status as obsolete before finalizing designs. Confirm RoHS compliance details and specific datasheet revisions. Ensure the 8-SOIC footprint matches the target PCB layout. Check for alternative sourcing channels due to end-of-life status.

Selection Notes

Select this component when low drive current and high gain are required in a compact form factor. The 100kb/s speed suits moderate data rates. Consider the open-collector nature of the output for circuit compatibility. Evaluate thermal performance within the specified operating range.

Part Context
