S25-50

The S25-50 is especifically recommended as an HF, SSB output or driver from a 50 volts supply. This superbly linear device is ruggedized and emitter ballasted, and may be operated class A, AB or C in output or driver stages.

Some absolute maximum ratings of S25-50 have been concluded into several points as follow. (1)Its maximum power dissipation at 25°C case temperature would be 80W. (2)Its collector to emitter voltage would be 110V. (3)Its emitter to base voltage would be 4.0V. (4)Its collector current would be 5A. (5)Its storage temperature range would be from -65°C to 150°C. (6)Its operating junction temperature would be 200°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of S25-50 are concluded as follow. (1)Its power output PEP would be min 25W. (2)Its power input PEP would be max 1W. (3)Its power gain would be typ 15dB. (4)Its collector efficiency would be typ 55%. (5)Its output VSWR capability would be max :1. (6)Its breakdown voltage emitter to base would be min 4V with conditions of Ic=0A and Ie=10mA. (7)Its breakdown voltage collector to emitter would be min 110V with conditions of Vbe=0 and Ic=100mA and it would be min 65V with conditions of Ib=0A and Ic=100mA. (8)Its 3rd order products would be typ -35dBc and max -33dBc. (9)Its capacitance collector to base would be min 55pF with conditions of f=1MHz and Vcb=50V. (10)Its DC current gain would be min 10 and max 100 with conditions of Vce=5V and Ic=500mA. (11)Its thermal resistance would be max 2.2°C/W. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
