Philips Semiconductors Product specification

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.
