2SA1511

      The 2SA1511 is designed as PNP/NPN epitaxial planar silicon transistors.Its typical applications contains switchong circuits,inverter circuits,interface sircuits and driver circuits.
      2SA1511 has two features.The first one is about its om-chip bias resistance which means R1=4.7.The second one is about its small-sized package which would be SPA.That are all its features.
      Some absolute maximum ratings of 2SA1511 at Ta=25°C have been concluded into several points as follow.The first one is about its collector to base voltage which would be -50V.The second one is about its collector to emitter voltage which would also be -50V.The third one is about its emitter to base voltage which would be -5V.The fourth one is about its collector current which would be -100 mA.The fifth one is about its collector dissipation which would be 300 mW.The sixth one is about its collector current(pulse) which would be -200 mA.The seventh one is about its junction temperature which would be 150 °C.The last one is about its storage temperature which should be within -55 to +150 °C.
      Also there are some important electrical characteristics of 2SA1511 at Ta=25°C about it.The first one is about its collector cutoff voltage which would be -0.1max uA.The second one is about its emitter cufoff voltage which would also be -0.1max uA.The third one is about its DC current gain which would be 100min.The fourth one is about its gain-bandwidth product which would be 250typ MHz.The fifth one is about its output capacitance which would be 3.7 pF.The sixth one is about its collector to emitter saturation voltage which would be -0.1typ V and be -0.3max V.The seventh one is about its collector to base breakdown voltage which would be -50min V.The eighth one is about its collector to emitter breakdown voltage which would also be -50 V.The ninth one is about its input OFF voltage which would be (-)0.4min V and (-)0.55typ V and (-)0.8max V.The tenth one is about its input On-state voltage which would be (-)0.6min V and (-)1.0typ V and (-)2.0max V.
