2SC2139A

The 2SC2139A is designed as silicon NPN power transistors with typical applications of switching regulator applications and high speed DC-DC converter applications.
2SC2139A has two features.The first one is that it would be with TO-3 package.The second one is that it would have high voltage and high speed.That are all the features.
Some absolute maximum ratings of 2SC2139A(Ta=25°C) have been concluded into several points as follow.The first one is about its collector-base voltage which would be 500V with condition of open emitter.The second one is about its collector-emitter voltage which would be 400V with condition of open base.The third one is about its emitter-base voltage which would be 7V with condition of open collector.The fourth one is about its collector current which would be 10A.The fifth one is about its collector power dissipation which would be 100W.The sixth one is about its junction temperature which would be which would be +175°C.The last one is about its storage temperature which would be from -55 to 175°C.
Also some important electrical characteristics(Tj=25°C unless otherwise specified) about 2SC2139A.The first one is about its collector-emitter breakdown voltage which would be 400(min) V with condition of Ic=10mA, Ib=0.The second one is about itscollector-base breakdown voltage which would be 500(min) V with condition of Ic=1mA, Ie=0.The third one is about itsemitter-base breakdown voltage which would be 7(min) V with condition of Ie=1mA, Ic=0.The fourth one is about itscollector-emitter saturation voltagewhich would be 1.0(max) V with condition of Ic=5A, Ib=1A.The fifth one is about itsbase-emitter saturation voltage which would be 1.5(max) V with condition of Ic=5A, Ib=1A.The sixth one is about itscollector cut-off current which would be 0.1(max) mA with condition of Vcb=500V, Ie=0.The seventh one is about itsemitter cut-off current which would be 0.1(max) mA with condition of Veb=7V, Ic=0.And so on.For more information please contact us.
