DESCRIPTION
Dual Schottky rectifier suited to Switch Mode
Power Supplies and other Power Converters.
This device is intended for use in low and medium
voltage operation, and particulary, in high fre-
quency circuitries where low switching losses are
required (free wheeling and polarity protection).
