FEATURES AND BENEFITS

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).
