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 BY329 series is supplied in the
conventional
leaded
SOD59
(TO220AC) package.
