DESCRIPTION

These Microsemi PIN diodes are perfect for high power switching

applications where high isolation, low loss, low distortion characteristics, and

high power handling capability are critical. These PIN diodes utilize

Microsemi’s SOGO passivation process for superior stable high voltage

operation. The package is a modified DO-4 structure for ease of mount down

with excellent thermal properties. No thin internal straps are used for

electrical connections. A surge current of 150 amperes at half sine 8.3 ms is

easily handled.
