Product specification

Ultra fast high-voltage soft-recovery

controlled avalanche rectifier

BY9200 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

• Colour television and monitors up

to 130 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.
