2SK2884

      The 2SK2884 is designed as silicon N-channel MOS type (-MOSIII) with typical applications of chopper regulator, DC-DC converter applications.
      It has four features.The first one is that it would have low drain-source ON-resistance which means Rds (ON) = 1.9 (typ.).The second one is that it would have high forward transfer admittance which means |Yfs| = 3.8 S (typ.).The third one is that it would have low leakage current which means Idss = 100 A (max) (VDS = 640 V).The fourth one is that it would have enhancement mode which means Vth = 2.0~4.0 V (VDS = 10 V, ID = 1 mA).That are all the features.
      Some absolute maximum ratings (Ta = 25°C) have been concluded into several points as folllow.The first one is about its drain-source voltage which would be 800 V.The second one is about its drain-gate voltage (RGS = 20 k) which would be 800 V.The third one is about its gate-source voltage which would be ±30 V.The fourth one is about its drain current which would be 5 A for DC and would be 15 A for pulse.The fifth one is about its drain power dissipation (Tc = 25°C) which would be 100 W.The sixth one is about its single pulse avalanche energy which would be 370 mJ.The seventh one is about its avalanche current which would be 5 A.The eighth one is about its repetitive avalanche energy which would be 10 mJ.The ninth one is about its channel temperature which would be 150 °C.The last one is about its storage temperature range which would be from -55 to 150 °C.
      Something should be noted that using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings.And also about its drain current it should be noted that ensure that the channel temperature does not exceed 150°C.And about its single-pulse avalanche energy it should be noted that Vdd = 90 V,Tch = 25°C(initail), L = 27 mH, Rg = 25 , Iar = 5 A.About its repetitive avalanche energy it should be noted that repetitive rating: pulse width limited by maximum channel temperature.After all this transistor is an electrostatic-sensitive device.Please handle with caution.
