Fast high-voltage soft-recovery
rectifiers
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.

Data Sheet Status
Objective specification This data sheet contains target or goal specifications for product development.
Preliminary specification This data sheet contains preliminary data; supplementary data may be published later.
Product specification This data sheet contains final product specifications.
Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
Application information
Where application information is given, it is advisory and does not form part of the specification.
LIFE SUPPORT APPLICATIONS
These products are not designed for use in life support appliances, devices, or systems where malfunction of these
products can reasonably be expected to result in personal injury. Philips customers using or selling these products for
use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such
improper use or sale.
