W30M40CT

      W30M40CT is a kind of 30A schottky barrier rectifier.It is intended for for applcations requiring low forward voltage drop and switching power supply, dc-dc converter, free-wheeling diode, battery charging, polarity protection application.
      Here you can get some information about the features.First,plastic material meets UL94V-0.The second is metal silicon junction.The third is very low forward voltage drop.The fourth is high current and high surge capability.Then is guarding for over voltage protection.Next is lead solderable per MIL-STD202,method 208 guaranteed.The sixth is lead temperature for soldering purpose 250 Max for 10 second.At last ,the weight is 5.6 gram (approximately).
      What comes next is about the absolute maximum ratings.The V_RRM (Repetitive Peak Reverse Voltage) is 40 V.The V_R (Maximum DC Reverse Voltage) is 40 V.The I_F(AV) (Average Forward Current @ T_C = 100) is 15 A for per diode and 30 A for total device.The I_FSM (Non-Repetitive Peak Surge Current (Surge applied at rated load conditions half sinewave,single phase, 60Hz)) is 275 A.The E_as (Non-Repetitive Avalanche Energy) is 17.5 mJ at T_C=25,V_dd = 15V,L=18uH.The T_J (Maximum Junction Temperature) is from - 65 to 125.The T_STG (Storage Temperature Range) is from - 65 to 150. Then is about the thermal characteristics.The R_JC (Maximum Thermal Resistance, Junction-to-Case ( per diode)) is 1.5 /W.
      The following is about the electrical characteristics.The maximum I_R (Reverse Leakage Current) is 1 mA at V_R = V_RRM,TC=25 and is 50 mA V_R = V_RRM,T_C=125.The maximum V_F (Forward Voltage Drop) is 0.50 V at I_F = 15 A,T_C = 25,0.45 V at I_F = 15 A,T_C = 125,0.60 V at I_F = 30 A,T_C = 25 and 0.55 V at I_F = 30 A,T_C = 125.The typical C_T (Junction Capacitance @ f_T=1MHZ , V_R=4V , T_j =25) is 750 pF.
