GENERAL DESCRIPTION
Glass-passivated double diffused
rectifier diode featuring fast forward
recovery and low forward recovery
voltage. The device is intended for
use in multi-sync monitor deflection
circuits up to 64kHz. The device is
designed to withstand transient
reverse voltages up to 1700V.
The BY479X series is supplied in
the conventional leaded SOD113
package.
