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.
The cathode is marked by a black band on the body.
BYX90G
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.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
