DESCRIPTION
These plastic encapsulated general purpose transistor* are
designed for applications requiring high breakdown voltage
and low capacitance.
The E-line package is formed by Injection moulding a SILICONE
plastic specially selected to provide a rugged one-piece encap-
sulation resistant to severe environments and allow the high
junction temperature operation normally associated with metal
can devices.
E-line encapsulated devices are approved for use in military.
Industrial and professional equipments.
Alternative lead configurations are available as plug-in replacements of TO-5/39 and TO-18
metal can types, and for flat mounting.
