General Information
The markets of portable communications, computing and video equipment are
challenging the semiconductor industry to develop increasingly smaller electronic
components.
Bourns offers Bridge Rectier Diodes for rectication applications in compact chip package
0.41 ˝ x 0.32 ˝ size format, which offers PCB real estate savings and are considerably smaller
than standard parts. The Bridge Rectier Diodes offer a forward current of 4 A with a choice
of repetitive peak reverse voltages between 600 V and 1000 V.
