SFH1690CT

Overview

The SFH1690CT is a single-channel phototransistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It provides electrical isolation with a maximum output voltage of 55V and an isolation voltage of 5300Vrms. The device features a typical forward voltage of 1.1V and supports a maximum DC forward current of 60 mA. It offers a current transfer ratio ranging from 100% to 200% at 1 mA input. The component operates within a temperature range of -55°C to 100°C and utilizes a 4-SMD, gull-wing package for surface mount installation.

Feature Summary

High isolation voltage capability of 5300Vrms for safe electrical insulation
Low coupling capacitance designed for efficient signal transmission
High current transfer ratio ensuring reliable phototransistor output performance

Applications

Signal transmission in isolated circuits
Safe electrical insulation applications
General purpose optocoupler tasks requiring high isolation

Procurement Notes

Verify the specific suffix 'CT' corresponds to the tape and reel packaging configuration required for your assembly line. Confirm that the 4-SMD gull-wing footprint matches your PCB design constraints. Ensure the operating temperature range up to 100°C aligns with your system's thermal environment requirements before finalizing procurement.

Selection Notes

Select this component when high isolation voltage and low coupling capacitance are critical for signal integrity. The surface mount package facilitates automated assembly processes. Consider the current transfer ratio specifications relative to your load requirements. Verify compatibility with standard SOP-4 footprints if alternative sourcing is necessary.
