BF391 BF392 BF393 NPN Silicon Planar sistors 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 encapsulation resistant to severe environments and allow the high junction temperature operation normally associated with metal can devices. PLASTIC E-LINE <TO-92) 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.
