Product specification
Ultra fast high-voltage soft-recovery
controlled avalanche rectifiers
BY8200 series
FEATURES
Plastic package
Glass passivated
High maximum operating
temperature
Low leakage current
Excellent stability
40% overvoltage allowed during
5 sec
Guaranteed avalanche energy
absorption capability
Very low reverse recovery time
Soft-recovery switching
characteristics
Compact construction.
APPLICATIONS
For colour television and monitors
up to 90 kHz (indication)
High-voltage applications for:
multipliers
diode-split-transformers
(FBT's).
DESCRIPTION
Plastic package, using glass
passivation and 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 should be used in an
insulating medium such as resin, oil
or SF6 gas.
