Fast high-voltage soft-recovery rectifiers
BY8400 series
FEATURES
Glass passivated
High maximum operating
temperature
Low leakage current
Excellent stability
Soft-recovery switching
characteristics
Compact construction.
APPLICATIONS
For colour television and monitors
up to 25 kHz
High-voltage applications for:
Multipliers
Slot-wound diode-split-
transformers.
DESCRIPTION
Rugged glass package, using a high
temperature alloyed construction.
This package is hermetically sealed
and fatigue free as coefficients of
expansion of all used parts are
matched.
The package is designed to be used
in an insulating medium such as
resin, oil or SF6 gas.
