2SK443

        2SK443 is a kind of N-channel silicon field effect transistor which has four unique features : The first one is large /yfs/. The second one is small ciss. The third one is very low noise figure. The forth one is very small-sized package permitting 2SK443-applied sets to be small-sized.
       There are some absolute maximum ratings of 2SK443. Drain to source voltage(V_DSS) is 15 V. Gate to drain voltage (V_GDS) is -15 V. Gate current (I_G) is 10 mA. Drain current(I_D) is 50 mA. Power dissipation(P_D) is 200 mW. Junction temperature (T_j) is 125.Storage temperature (T_stg) is -55 to +125. There are also some electrical characteristics about it . Gate-to drain(V_(BR)CDS) is -15 V min when I_D is 10A and V_DS is 0. Common-source gate(I_GSS) is -1.0 nA typ when V_GS is -10 V and V_DS is 0. Gate-to -source cutoff voltage(V_GS(off) ) is -0.9 V min and -2.0 V typ when V_DS is 5 V and I_D is 100A. Drain current (I_DSS) is 5.0 mA min and 38.0 mA when V_DS is 5V and V_GS is 0. Input capacitance (Ciss) is 9.0 pF typ when V_DS is 5V,V_GS is 0 and f is 1MHz. Reverse transfer capacitance(Crss) is 2.8pF when V_DS is 5V,V_GS is 0 and f is 1MHz. Noise figure(N_F) is 1.5 dB typ when V_DS is 5V, Rg is 1K, I_D is 1mA and f is 1KHz.
     In a word , this is just a simple introduction of this kind of product, and if you are interested in 2SK443 or you want to know detailed information about it, please come to know more about our web. Thanks for your concern of our information!
