HAZARDOUS MATERIAL WARNING
The ceramic portion of the device between
leads and mounting surface is beryllium oxide,
BeO. Beryllium oxide dust is toxic when in-
haled. Care must be taken during handling
and mounting to avoid damage to this area .
These devices must never be thrown away
with general industrial or domestic waste.

Dimensions in Millimeters and (Inches)
NOTE: These two parts comprise a symmetric pair of RF
power transistors and meet the same electrical
specifications. The device pin-outs are the mirror image
of each other to allow ease of use as a push-pull pair.
