SGSF313PI

The SGSF313PI is designed as one kind of high voltage NPN fast switching transistors to be used as switch in high frequency off-line (200V mains) switching power supplies for consumer applications like sets VCR's and monitors. Its typical applications include switch mode power supplies, flyback and forward single transistor low power converters.

SGSF313PI has five features. (1)High voltage capability (450V Vceo). (2)Very high switching speed tf=35ns typical at Ic=2.5A and Ib1=0.5A and Vboff=-5V. (3)Low saturation voltage. (4)Complete characterization at 100°C. (5)UL recognised ISOWATT220 package. Those are all the main features.

Some absolute maximum ratings SGSF313PI have been concluded into several points as follow. (1)Its collector to emitter voltage at Vbe=-2.5V would be 1000V. (2)Its collector to emitter voltage at Vbe=0 would be 1000V. (3)Its collector to emitter voltage Ib=0 would be 450V. (4)Its emitter to base voltage Ic=0 would be 10V. (5)Its collector current would be 7A. (6)Its collector peak current tp<5ms would be 10A. (7)Its base current would be 3A. (8)Its base peak current tp<5ms would be 6A. (9)Its total dissipation at Tc=25°C would be 35W. (10)Its storage temperature range would be from -65°C to 150°C. (11)Its max operating junction temperature would be 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics SGSF313PI are concluded as follow. (1)Its collector cutoff current Vbe=0 would be max 10uA and max 100uA at Tj=125°C. (2)Its collector cutoff current Ib=0 would be max 100uA. (3)Its collector to emitter sustaining voltage would be min 450V. (4)Its collector to emitter saturation voltage would be max 0.5V at Ic=1A and Ib=0.1A and would be max 0.45V at Ic=2A and Ib=0.4A. (5)Its base to emitter saturation voltage would be max 1.25V at Ic=2A and Ib=0.4A. And so on.
