2SK2237

      2SK2237 is a kind of silicon N channel MOS type.It is widely used in the field of high speed,high switching,chopper regulator,DC-DC converter and motor drive applications.There are four features.First,it has low drain-source on resistance:R_DS(ON)=0.6 (Typ.).Secondly,it has high forward transfer admittance:Y_fs=5.5s(Typ.).Thirdly,it has low leakage current:IDDS=100A(Max.)(V_DS=500V).Fourthly,the enhancement is V_th=2.0~4.0V(V_DS=10V,I_D=1mA).
      What comes next is the maximum ratings of 2SK2237.The V_DSS (drain-source voltage) is 500 V.The V_DGR (drain-gate voltage) is 500 V at R_SS=20k.The V_GSS (gate-source voltage) is ±30 V.The I_D (drain current of DC) is 7A and the I_DP (drain current of pulse) is 28A.The P_D (drain power dissipation) is 45W at Tc=45.The T_ch (channel temperature) is 150 and the T_stg (storage temperature) is from  -55 to 150.Then is about the thermal characteristics.The maximum P_th(ch-c) (thermal resistance,channel to case) is 2.77/W and the maximum P_th(ch-a) (thermal resistance,channel to ambient) is 62.5/W.
      The following is the electrical characteristics of 2SK2237.The maximum I_GSS (gate leakage current) is ±10 A at V_GS=±25v,VDS=0V.The minimum V(BR)GSS (gate-source breakdown voltage) is ±30V at IG=±100A,VDS=0V.The maximum I_DSS (drian cut-off current) is 100A at V_DS=500V,V_GS=0V.The minimum V_(BR)DSS (drain-source breakdown voltage) is 500V at I_D=10mA,V_GS=0V.The minimum V_th (gate threshold voltage) is 2.0V and the maximum is 4.0V at V_DS=10V,I_D=1mA.The typical R_DS(ON) (drain-source on resistance) is 0.6 and the maximum is 0.8 at V_GS=10V,I_D=4A.The minimum /Yfs/(forward transfer admittance) is 3.0S and the typical is 5.5S at V_DS=10V,I_D=4A.Following the condition that V_DS=10V,V_GS=0V,F=1MHz,the typical Ciss (input capacitance) is 1300pf,the typical C_rss (reverse transfer capacitance) is 80pf and the typical Coss (output capacitance) is 360pf.Under the condition that the V_DD=400V,V_GS=10V,I_D=7A,the typical Q_g (total gate charge (gate-source plus gate-drain)) is 30 nC,the typical Q_gs (gate-source charge) is 18 nC and the typical Q_gd ( gate-drain charge) is 12 nC.
