GENERAL DESCRIPTION
Glass-passivated double diffused rectifier diodes featuring low forward voltage drop, fast reverse recovery and soft
recovery characteristic. The devices are intended for use in TV receivers, monitors and switched mode power supplies.
The BY229F series is supplied in the conventional leaded SOD100 package.
The BY229X series is supplied in the conventional leaded SOD113 package.
