2SK1645

      The 2SK1645 is a very good product. If you want to use it you must learn about it rightly. Here you can know some features about it. The 2SK1645 has four features. Please pay attention to them. The first feature of the 2SK1645 is that it has lowest phase noise. The second feature of the 2SK1645 is that the chip surface is covered with the highly reliable protection film. The third feature of the 2SK1645 is super miniaturized plastic-mold package (CP4). The last feature of the 2SK1645 is that automatic surface mounting is available.
      The absolute maximum ratings of the 2SK1645 can make you clear of the 2SK1645, I am very glad to show you the absolute maximum ratings of the 2SK1645. It has six absolute maximum ratings. The first absolute maximum rating is drain-to-source voltage, which is 6.0 V. The second absolute maximum rating is gate-to-source voltage, which is -5.0V. The third absolute maximum rating is drain current, which is 100mA. The fourth absolute maximum rating is allowable power dissipation, which is 200 mW. The fifth absolute maximum rating is junction temperature, which is 150 °C. The sixth absolute maximum rating is storage temperature which is -55 to +150 °C.
      Next I will show you some electrical characteristics of the 2SK1645. And the condition is 25°C, unless other is noted. The first electrical characteristics of the 2SK1645 is gate-to-source breakdown voltage, which is -5.0 V (typ.) on the condition of IGS=--10,The second electrical characteristics of the 2SK1645 is saturated drain current , which is 60 mA (typ.) on the condition of VDS=3V, VGS=0. The third electrical characteristics of the 2SK1645 is gate-to-source cutoff voltage, which is -5.0 V (max.) on the condition of VDS=3V, ID=100A . The fourth electrical characteristics of the 2SK1645 is forward transfer admittance, which is 40mS (typ.) on the condition of VDS=3V, ID=10mA . The fifth electrical characteristics of the 2SK1645 is minimum noise figure, which is 2.5 dB (typ.) on the condition of VDS=3V, ID=10mA, f=12GHz. The sixth electrical characteristics of the 2SK1645 is associated gain, which is 5.5 dB (typ.) on the condition of VDS=3V, ID=10mA, f=12GHz. The seventh electrical characteristics of the 2SK1645 is maximum available gain, which is 7.0dB (typ.) on the condition of VDS=3V, ID=10mA, f=12GHz.
