General Information

Electrical Characteristics (@ TA= 25 °C Unless Otherwise Noted)

The markets of portable communications, computing and video equipment are challenging the semiconductor industry to develop

increasingly smaller electronic components. Bourns offers Schottky Rectifier Diodes for rectification applications, in compact chip package

1206 size format, which offer PCB real estate savings and are considerably smaller than most competitive parts. The Schottky Rectifier

Diodes offer a forward current of 2 A with a repetitive peak reverse voltage of 20 V up to 100 V.

Bourns®Chip Diodes conform to JEDEC standards, are easy to handle on standard pick and place equipment and their flat configuration

minimizes roll away.
