High-voltage soft-recovery
controlled avalanche rectifier
FEATURES
• Glass passivated
• High maximum operating
temperature
• Low leakage current
• Excellent stability
• Soft-recovery switching
characteristics
• Guaranteed avalanche energy
absorption capability.
APPLICATIONS
• High-voltage rectification at high
frequencies
• Sub-component for very high
voltage rectifiers, for example, in
X-ray and radar equipment.
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.
